Hi @CamBlackwood. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- If you accidentally deleted the DATABASE_URL from your production environment, you can retrieve it from the .wasp/out/server/.env file as mentioned in Github Issue #940 (https://github.com/wasp-lang/wasp/issues/940). Prisma supports this file for environment variables. However, if you can't find it there, you might need to retrieve it from your hosting provider. For example, if you're using Heroku, you can get it with the command heroku config:get DATABASE_URL -a <app_name> as mentioned in Github Issue #215 (https://github.com/wasp-lang/wasp/issues/215). Remember to be careful with your DATABASE_URL as it contains sensitive information. It's not recommended to store the production database URL locally due to security reasons. After retrieving your DATABASE_URL, you can set it back in your production environment. Be sure to remove it from your local .env.server file when you're done debugging to avoid accidentally executing commands against your production database. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble. Don't worry though, I've pinged my support and they will try to fix me up! :technologist: Perhaps try again in 15mins?

@kapa.ai I'm using fly via the wasp cli

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If you're using Fly.io via the Wasp CLI and you've accidentally deleted your DATABASE_URL, you can retrieve it by using the flyctl CLI. Here's how you can do it: 1. Make sure you are logged in with flyctl CLI. You can check if you are logged in with flyctl auth whoami, and if you are not, you can log in with flyctl auth login as mentioned here (https://wasp-lang.dev/docs/advanced/deployment/manually#flyio-server-and-database). 2. Once you're logged in, you can retrieve your DATABASE_URL by running the following command:

flyctl secrets list --app <app-name>

flyctl secrets list --app <app-name>

Replace <app-name> with the name of your app. This command will list all the secrets for your app, including the DATABASE_URL. After retrieving your DATABASE_URL, you can set it back in your production environment. Be sure to remove it from your local .env.server file when you're done debugging to avoid accidentally executing commands against your production database. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai but as I deleted it, it's not available in the list

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If you've deleted the DATABASE_URL from your Fly.io environment and it's not available in the secrets list, you might need to recreate it. When you first deployed your app with Wasp onto Fly.io, you should have received your Fly database username and password. If you still have these credentials, you can recreate your DATABASE_URL in the following format:

DATABASE_URL=postgres://<user>:<pw>@localhost:5432/<db_name>?sslmode=disable

DATABASE_URL=postgres://<user>:<pw>@localhost:5432/<db_name>?sslmode=disable

Replace <user>, <pw>, and <db_name> with your actual database username, password, and database name respectively. If you don't have these credentials, unfortunately, Fly.io doesn't provide a way to retrieve them again as mentioned in Github Issue #908 (https://github.com/wasp-lang/wasp/issues/908). In this case, you might need to create a new database and update your application to use the new DATABASE_URL. Please remember to store these credentials securely and avoid deleting them in the future. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai now that it's deloyed, I seem to be getting CORS issues in production and my sign in/log in buttons have disappeared.

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- It seems like you're experiencing two separate issues: CORS issues and disappearing sign in/log in buttons. 1. CORS Issues: CORS (Cross-Origin Resource Sharing) issues often occur when your server and client are not properly configured to communicate with each other. In Wasp, you need to set the WASP_WEB_CLIENT_URL and WASP_SERVER_URL environment variables correctly for your production environment. These URLs are used to properly configure the Same-Origin Policy (CORS) headers. You can find more information about these environment variables in the Wasp documentation (https://wasp-lang.dev/docs/advanced/deployment/manually#environment-variables). If you're still experiencing CORS issues after setting these variables, it might be related to a known issue in Wasp as mentioned in Github Issue #1303 (https://github.com/wasp-lang/wasp/issues/1303). 2. Disappearing Sign In/Log In Buttons: This could be due to a number of reasons. If you recently migrated from Wasp 0.11 to Wasp 0.12, there might be a period where your app is not working completely as mentioned in the Wasp documentation (https://wasp-lang.dev/docs/migrate-from-0-11-to-0-12#1-migrate-to-the-new-auth-system). During this period, new users will be able to sign up, but existing users won't be able to log in, and already logged in users will be logged out. If this is the case, you need to migrate your production database data to get everything back to normal. If you didn't recently migrate, the issue might be related to your app's code. For example, in Discord support thread (https://discord.com/channels/686873244791210014/1217941277979574315), a user reported that their log in tab disappeared because the isUserLoading variable was truthy. Without more specific information about your app's code and configuration, it's hard to provide a more precise solution. However, I hope this general guidance helps you troubleshoot your issues. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai I am using wasp 0.13 and this only started happening after I made a mistake in the deployment where I made the mistake with the database url

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If the issues started after a mistake with the DATABASE_URL during deployment, it's possible that your application is not able to connect to the database properly, which could cause various issues including the disappearance of the sign in/log in buttons. Here are some steps you can take to troubleshoot: 1. Check your DATABASE_URL: Make sure that your DATABASE_URL is correctly set in your Fly.io environment. You can check it by running flyctl secrets list --app <app-name>. 2. Check your application logs: You can check your application logs to see if there are any error messages related to the database connection. You can view your Fly.io application logs by running flyctl logs --app <app-name>. 3. Check your application code: Make sure that your application code is correctly using the DATABASE_URL to connect to the database. In Wasp, the DATABASE_URL is typically used in the main.wasp file to configure the Prisma client. 4. Redeploy your application: If you've made changes to your DATABASE_URL or other environment variables, make sure to redeploy your application for the changes to take effect. You can redeploy your application by running wasp deploy <app-name>. If you're still experiencing issues after these steps, it might be helpful to provide more specific information about the error messages you're seeing or the changes you made to your DATABASE_URL. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai where specifically should I look in the main.wasp file?

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In the main.wasp file, you should look for the entity declarations and any query or action declarations that interact with your database. Here's an example of what you might see in a main.wasp file:

entity User {
  id Int @id @default(autoincrement())
  recipes Recipe[]
}

entity Recipe {
  id Int @id @default(autoincrement())
  title String
  description String?
  userId Int
  user User @relation(fields: [userId], references: [id])
}

query getRecipes {
  fn: import { getRecipes } from "@src/recipe/operations.ts",
  entities: [Recipe],
}

action addRecipe {
  fn: import { addRecipe } from "@src/recipe/operations.ts",
  entities: [Recipe],
}

entity User {
  id Int @id @default(autoincrement())
  recipes Recipe[]
}

entity Recipe {
  id Int @id @default(autoincrement())
  title String
  description String?
  userId Int
  user User @relation(fields: [userId], references: [id])
}

query getRecipes {
  fn: import { getRecipes } from "@src/recipe/operations.ts",
  entities: [Recipe],
}

action addRecipe {
  fn: import { addRecipe } from "@src/recipe/operations.ts",
  entities: [Recipe],
}

In this example, User and Recipe are entities that represent tables in your database. The getRecipes query and addRecipe action are operations that interact with your database. These operations are implemented in the @src/recipe/operations.ts file. If there's an issue with your DATABASE_URL, these operations might fail and cause various issues in your application, such as the disappearance of the sign in/log in buttons. You should also check any auth declarations in your main.wasp file, as these also interact with your database. For example:

app RecipeApp {
  title: "My Recipes",
  wasp: { version: "^0.13.0" },
  auth: {
    methods: { usernameAndPassword: {} },
    onAuthFailedRedirectTo: "/login",
    userEntity: User
  }
}

app RecipeApp {
  title: "My Recipes",
  wasp: { version: "^0.13.0" },
  auth: {
    methods: { usernameAndPassword: {} },
    onAuthFailedRedirectTo: "/login",
    userEntity: User
  }
}

In this example, the auth declaration configures authentication for your application using the User entity. If there's an issue with your DATABASE_URL, authentication might fail and cause the sign in/log in buttons to disappear. You can find more information about the main.wasp file in the Wasp documentation (https://wasp-lang.dev/docs/tutorial/project-structure#mainwasp). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai sorry, I mean should I by using process.env.DATABASE_URL in main.wasp?

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- No, you don't need to use process.env.DATABASE_URL in your main.wasp file. In Wasp, environment variables like DATABASE_URL are typically used in the .env files or set in the deployment environment, not directly in the main.wasp file. For example, during development, you can set DATABASE_URL in the .env.server file in the root directory of your Wasp project as mentioned in the Wasp documentation (https://wasp-lang.dev/docs/project/env-vars#defining-env-vars-in-development). When deploying your application, you should set DATABASE_URL in your deployment environment. If you're using Fly.io, you can set it using the flyctl CLI as mentioned in the Wasp documentation (https://wasp-lang.dev/docs/advanced/deployment/manually#4-deploying-the-database). Wasp and Prisma will automatically use the DATABASE_URL from the environment when connecting to the database. You don't need to manually read DATABASE_URL from the environment in your main.wasp file. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai I think the buttons don't appear must be because the loading is hanging, because it never completes. In that case, I think my database url must be wrong. I will try and fix that

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, if the loading never completes, it's possible that your application is not able to connect to the database due to an incorrect DATABASE_URL. Here are some steps you can take to fix your DATABASE_URL: 1. Check your DATABASE_URL format: The DATABASE_URL should be in the following format: postgres://<user>:<password>@<host>:<port>/<database_name>. Make sure that all parts of the URL are correct. 2. Check your database credentials: Make sure that the username, password, and database name in your DATABASE_URL are correct. You should be able to find these credentials from your database provider. 3. Check your database host and port: Make sure that the host and port in your DATABASE_URL are correct. If you're using a hosted database service, you should be able to find this information from your database provider. 4. Set your DATABASE_URL in your Fly.io environment: Once you've fixed your DATABASE_URL, you can set it in your Fly.io environment by running flyctl secrets set DATABASE_URL=<your_database_url> --app <app-name>. 5. Redeploy your application: After setting your DATABASE_URL, you should redeploy your application for the changes to take effect. You can redeploy your application by running wasp deploy <app-name>. If you're still experiencing issues after these steps, it might be helpful to provide more specific information about the error messages you're seeing or the changes you made to your DATABASE_URL. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai all the requests to my server app fail, but I can see in the console they're targeting the correct url. Could the database url still be wrong in that case?

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, even if your requests are targeting the correct server URL, they can still fail if the DATABASE_URL is incorrect. This is because the server needs to connect to the database to handle most requests, especially those related to authentication or data retrieval. If the server can't connect to the database due to an incorrect DATABASE_URL, these requests will fail. Here are some steps you can take to troubleshoot: 1. Check your DATABASE_URL: Make sure that your DATABASE_URL is correctly set in your Fly.io environment. You can check it by running flyctl secrets list --app <app-name>. 2. Check your application logs: You can check your application logs to see if there are any error messages related to the database connection. You can view your Fly.io application logs by running flyctl logs --app <app-name>. 3.

@kapa.ai DATABASE_URL was set 20 minutes ago and I've redeployed twice. Is there anything specific I should search for in logs?

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, when checking your application logs, you should look for any error messages related to the database connection. Here are some specific things to look for: 1. Errors related to DATABASE_URL: Look for any error messages that mention DATABASE_URL. This could indicate that your DATABASE_URL is not set correctly. 2. Errors from Prisma: Prisma is the database client used by Wasp. Look for any error messages from Prisma. These could indicate issues with the database connection or with your database schema. 3. Errors related to specific database operations: Look for any error messages related to specific database operations, such as queries or mutations. These could indicate issues with your database schema or with the data in your database. 4. Errors related to authentication: Since the disappearance of the sign in/log in buttons is related to authentication, look for any error messages related to authentication. These could indicate issues with your authentication setup. You can view your Fly.io application logs by running flyctl logs --app <app-name>. If you're still experiencing issues after checking your logs, it might be helpful to provide more specific information about the error messages you're seeing. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai I've tried deploying again and the DATABASE_URL does seem right... it's postgres://postgres:<pw>@<name>-db.flycast:5432/<name>_server

MEE6•3mo ago

Wohooo @CamBlackwood, you just became a Waspeteer level 8!

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The DATABASE_URL you've provided seems to be in the correct format. However, please note that <name>-db.flycast:5432 might not be the correct host for your database. Usually, the host should be something like localhost for a local database or a specific URL provided by your database service for a hosted database. If you're sure that the host is correct, another thing to check is whether your database is actually running and accessible. You can test this by trying to connect to your database using a database client. If you're still having issues, it might be helpful to check the error messages in your application logs again. Look for any error messages related to the database connection or DATABASE_URL. Remember to replace <pw>, <name>, and <name>_server with your actual database password, Fly.io app name, and database name respectively. If you're still experiencing issues after these steps, it might be helpful to provide more specific information about the error messages you're seeing or the changes you made to your DATABASE_URL. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai I've noticed this in the server logs -
Error: P1011: Error opening a TLS connection: unexpected EOF

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The error P1011: Error opening a TLS connection: unexpected EOF typically indicates an issue with establishing a secure connection to your database. This could be due to a variety of reasons such as network issues, incorrect database URL, or issues with the database server itself. Here are a few things you can try: 1. Check your DATABASE_URL: Ensure that your DATABASE_URL is correctly formatted and contains the right credentials. It should be in the format postgres://<user>:<password>@<host>:<port>/<database_name>. 2. Check your database server: Ensure that your database server is running and accessible. You can try connecting to it using a database client to test this. 3. Check your TLS settings: The error message indicates an issue with opening a TLS connection. If your database server requires a secure (TLS) connection, ensure that your DATABASE_URL includes the sslmode parameter with the appropriate value. For example, postgres://<user>:<password>@<host>:<port>/<database_name>?sslmode=require. 4. Check your application logs: Look for any additional error messages in your application logs that might provide more information about the issue. If you're still experiencing issues after these steps, it might be helpful to reach out to your database provider or the Wasp community for further assistance. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

CamBlackwoodOP•3mo ago

@kapa.ai regarding this - postgres://<user>:<password>@<host>:<port>/<database_name>?sslmode=require - is this normally best practice?

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, using sslmode=require in your DATABASE_URL is generally a good practice when your database server supports SSL/TLS, as it ensures that your database connections are secure. However, the exact sslmode value you should use depends on your specific database server and its configuration. The sslmode=require setting means that the client will attempt to use SSL/TLS but will still connect if the server does not support it. Here are the different sslmode values you can use: - disable: No SSL/TLS. - require: The client will attempt to use SSL/TLS but will still connect if the server does not support it. - verify-ca or verify-full: The client will verify the server's certificate against the CA certificates available in the system. If your database server requires SSL/TLS and also provides a CA certificate for verification, you might want to use sslmode=verify-ca or sslmode=verify-full for additional security. Remember to replace <user>, <password>, <host>, <port>, and <database_name> with your actual database credentials. You can find more information about these settings in the PostgreSQL documentation (https://www.postgresql.org/docs/current/libpq-ssl.html#LIBPQ-SSL-PROTECTION). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai how can I check what my password is?

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- For security reasons, it's not possible to retrieve your password in plain text once it's been set. Passwords are typically hashed before they're stored in the database, which is a one-way operation that can't be reversed. In Wasp, the ensurePasswordIsPresent(args) and ensureValidPassword(args) functions are used to check if a password is present and valid, but they don't provide a way to retrieve the password itself as mentioned in the Wasp documentation (https://wasp-lang.dev/docs/auth/username-and-pass#password). If you've forgotten your password, the typical solution is to reset it. This usually involves requesting a password reset link, which is sent to your email address. You can then use this link to set a new password. The exact process depends on how authentication is set up in your Wasp application. If you're trying to retrieve a database password, you'll likely need to reset it through your database provider. Please remember to update your DATABASE_URL if you change your database password. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai I was talking about the database URL password but just got it via the fly console, and verified it's correct, so I'm not sure what's going wrong with the database connection

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If you've verified that the password in your DATABASE_URL is correct, there could be other factors causing the database connection issue. Here are some additional steps you can take to troubleshoot: 1. Check the rest of your DATABASE_URL: Make sure that the rest of your DATABASE_URL is correct, including the username, host, port, and database name. 2. Check your database server: Ensure that your database server is running and accessible. You can try connecting to it using a database client to test this. 3. Check your TLS settings: If your database server requires a secure (TLS) connection, ensure that your DATABASE_URL includes the sslmode parameter with the appropriate value. For example, postgres://<user>:<password>@<host>:<port>/<database_name>?sslmode=require. 4. Check your application logs: Look for any additional error messages in your application logs that might provide more information about the issue. You can view your Fly.io application logs by running flyctl logs --app <app-name>. 5. Check your Fly.io configuration: Make sure that your Fly.io application is correctly configured to connect to your database.

@kapa.ai regarding the previous message, shoukd <database_name> be my "db" or my "server". It's currently my server

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The <database_name> in your DATABASE_URL should be the name of your database. In the context of a Wasp app deployed on Fly.io, it's typically the name of your server app with underscores. For example, if your server app is named my-app-server, the database name would be my_app_server. So your DATABASE_URL would look something like this:

postgres://<user>:<password>@<host>:<port>/my_app_server

postgres://<user>:<password>@<host>:<port>/my_app_server

Remember to replace <user>, <password>, <host>, and <port> with your actual database credentials. You can confirm your database name by connecting to your database on Fly.io and running the \l command, as mentioned in the Github issue (https://github.com/wasp-lang/wasp/issues/1464) you provided. This will list all databases, and you should be able to find your database name there. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai is it possible for me to roll back to a previous server deployment?

kapa.ai•3mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Rolling back to a previous server deployment is dependent on the deployment platform you are using. If you are using Fly.io, they do not currently support direct rollback to a previous version of your application. However, you can manually redeploy a previous version of your application by checking out the corresponding commit in your version control system (like Git), and then running the wasp deploy <app-name> command. If you are using Heroku, you can use their releases (https://devcenter.heroku.com/articles/releases) feature to rollback to a previous release. Please note that rolling back your server might not solve issues related to your database, as the state of your database won't be rolled back. If you made changes to your database schema, you might need to manually revert those changes. Remember to always backup your data before performing operations that could potentially affect your database. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai getting this when trying to deploy WARNING The app is not listening on the expected address and will not be reachable by fly-proxy. You can fix this by configuring your app to listen on the following addresses:

Let me check the knowledge base for you. One moment! :books: ---------------------- This warning message typically appears when your application is not configured to listen on the correct IP address and port that Fly.io expects. In a typical Node.js application, you might start your server with something like app.listen(port). However, when deploying on Fly.io, you need to make sure your application is listening on the correct IP address and port provided by Fly.io. You can do this by updating your server start script to something like this:

const port = process.env.PORT || 3000;
const address = process.env.IP || '0.0.0.0';
app.listen(port, address, () => {
  console.log(`Server is running on <http://${address}:${port}`>);
});

const port = process.env.PORT || 3000;
const address = process.env.IP || '0.0.0.0';
app.listen(port, address, () => {
  console.log(`Server is running on <http://${address}:${port}`>);
});

In this script, process.env.PORT and process.env.IP are environment variables provided by Fly.io. If these variables are not set (e.g., during local development), the server will default to listening on 0.0.0.0:3000. After updating your server start script, you should redeploy your application for the changes to take effect. You can redeploy your application by running wasp deploy <app-name>. Please note that the exact code might vary depending on how you're starting your server and what framework or library you're using. The above code is just a general example for a Node.js server. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

@kapa.ai I got this after running wasp deploy fly deploy

Let me check the knowledge base for you. One moment! :books: ---------------------- The warning message you're seeing typically indicates that your application is not listening on the IP address and port that Fly.io expects. When deploying on Fly.io, your application needs to listen on the IP address 0.0.0.0 and on the port specified by the PORT environment variable. Here's how you can do this in a typical Node.js application:

const express = require('express');
const app = express();
const port = process.env.PORT || 3000;

app.listen(port, '0.0.0.0', () => {
  console.log(`Server is running on port ${port}`);
});

const express = require('express');
const app = express();
const port = process.env.PORT || 3000;

app.listen(port, '0.0.0.0', () => {
  console.log(`Server is running on port ${port}`);
});

In this example, process.env.PORT is the port number provided by Fly.io. If this environment variable is not set (e.g., during local development), the application will default to listening on port 3000. Please note that the exact code might vary depending on your application and the libraries you're using. The above code is just a general example for an Express.js server. After updating your server configuration, you should redeploy your application for the changes to take effect. You can do this by running wasp deploy <app-name>. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @CamBlackwood, I seem to be having a bit of trouble.

Hey @CamBlackwood could you maybe TLDR this for me? On the topic of restoring the connection URL: use the same instructions to rebuild the URL: https://github.com/wasp-lang/learning-materials?tab=readme-ov-file#running-wasp-db-studio-on-production-db But you need to tweak it a bit:

postgres://<username>:<pw>@<db-app-name>.flycast:5432/<db-name>?sslmode=disable

postgres://<username>:<pw>@<db-app-name>.flycast:5432/<db-name>?sslmode=disable

The crucial difference being the host <db-app-name>.flycast:5432
