Hi @lazi. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base.

----------------------
I can see you're having issues with redeploying your Wasp project to Fly.io. Based on the error message, there seems to be a problem during the client deployment process.

Here are a few potential solutions to try:

Update your Wasp version
- Some deployment issues were fixed in newer Wasp versions. For example, version 0.12.4 fixed a specific client deployment issue:

🙋questionsFailure to deploy client with Wasp CLI

Check your Node.js version
- You're using Node.js v22.12.0, which might be too new for Wasp. Wasp has had issues with certain Node versions in the past. Try using an older, more stable version like Node.js 18 using NVM:

🙋questionsNode version conflict between wasp and astro

Try cleaning your project before redeploying:

🙋questionsCant find: src/shared/constants.ts file? Stripe connect.

Check environment variables
- Make sure all necessary environment variables are properly set for your deployment.
Add organization flag
- If you're using WSL on Windows or have multiple Fly.io organizations, try adding the flag:

GitHub Issue

If the issue persists, you might need to check the generated code in the directory to see if there are any specific errors in your client code that might be causing the deployment to fail.

kapa.ai•4/8/25, 11:41 AM

Note that Fly.io deployments can sometimes be flaky, and the Wasp team is aware of issues with error handling during deployment. They're working on improving how deployment errors are handled to make it clearer what went wrong and how to proceed.

GrimmOP•4/8/25, 1:11 PM

Windows 11 with WSL2 (Ubuntu) - also on the nodejs i did have some changes.

The problem seemed to be with my client build/deployment - it succesfully passes the server deployment part (and it seems to be error handling errors mostly? )

I tried (and covered all of them) but then I was getting to the above mentioned error that i couldn't get past.

Mmiho Could you retry with `0.16.2`? Install it with `curl -sSL https://get.wasp.sh/in...

GrimmOP•4/8/25, 1:12 PM

BUT ! This worked for me - I used wasp 0.16.2 and it deployed it properly with no errors (after also reverting my latest changes on fixing the above mentioned errors)

GrimmOP•4/8/25, 1:12 PM

Thank you

miho•4/8/25, 1:13 PM

It seems that we have some issues with the deployment command in the latest Wasp version. Could you try one more time deploying with the latest version and share the full error log with me in the DMs?

kapa.ai•6/4/25, 6:48 PM

----------------------
The error message "Invalid region code mia. Please specify a valid 3 character region id" means that the region code you provided (mia) is not recognized by Fly.io as a valid region. Region codes must be valid 3-character identifiers supported by Fly.io.

How to fix:

**Find the correct region code:** You can get the list of all available Fly.io regions by running:```flyctl platform regions```Or, if you want to do it through Wasp CLI, run:```wasp deploy fly cmd platform regions --context server```[Fly.io Regions in Wasp Docs](<https://wasp-lang.dev/docs/advanced/deployment/cli#flyio-regions>)
**Use a valid region code:** Once you have the list, pick the region code that best fits your needs (for example, "iad" for US East, "fra" for Frankfurt, etc.), and use it in your deploy command:```wasp deploy fly launch my-wasp-app <region>```Replace `<region>` with the valid 3-character code you found.

If you need more details about Fly.io regions, you can also check the Fly.io regions documentation.

Let me check the knowledge base for you again. One moment!

kapa.ai•6/4/25, 6:50 PM

----------------------
Based on your output, you are using the correct region code ( for Frankfurt) as listed by . However, Wasp is still reporting "Invalid region code fra."

From the knowledge sources, here are some things to check:

**Wasp CLI Version**: Make sure you are using a recent version of Wasp. There have been bug fixes related to deployment and region handling in recent releases. You can check your version with `wasp version` and upgrade if needed as described in the docs and Discord threads. [Discord: Issue with deploying my wasp app to fly.io](<https://discord.com/channels/686873244791210014/1223671727943319584>)
**Region Code Format**: The region code should be a 3-character code, which `fra` is. The docs confirm this is the correct format. [Wasp Docs: Fly.io Regions](<https://wasp-lang.dev/docs/advanced/deployment/cli#flyio-regions>)
**Command Syntax**: The correct syntax for launching is:```wasp deploy fly launch <app-name> <region>```For your case:```wasp deploy fly launch creativefeedback fra```Make sure there are no extra spaces or line breaks between the app name and region code.
**Organization Flag**: If you are a member of multiple Fly.io organizations, you may need to specify the organization with `--org <org-slug>`. [Wasp Docs: Deploying with the Wasp CLI](<https://wasp-lang.dev/docs/advanced/deployment/cli#deploying>)

If you have confirmed all of the above and the error persists, the knowledge sources do not provide a direct solution for this specific issue. It may be a bug or a temporary issue with the Wasp CLI or Fly.io integration.

kapa.ai•6/4/25, 6:50 PM

Next Steps:

Double-check your Wasp version and upgrade if necessary.
Try specifying the organization with if applicable.
If the problem continues, consider opening an issue on the Wasp GitHub or asking in the Wasp Discord for further troubleshooting, as this may be an edge case not covered in the current documentation.

@kapa.ai Can you help me out with this? seems like pg-boss fails

message.txt14.14KB

kapa.ai•9/17/25, 11:15 AM

Let me check the knowledge base for you again. One moment!

kapa.ai•9/17/25, 11:15 AM

----------------------
Certainly! Based on the knowledge sources, the issue where pg-boss fails to start is a known problem that several Wasp users have encountered, especially on macOS (including M1/M2 chips). The error typically looks like this:

This means that pg-boss (which Wasp uses for background jobs) is unable to connect to your Postgres database. Here are the main findings and troubleshooting steps from the community and Wasp team:

---

Database Connectivity

Ensure your Postgres database is running and accessible on port 5432.
Run in one terminal and keep it running, then in another terminal run for your app. Both need to be running in parallel for things to work properly.
You can check if the database is accessible by running while the DB is running. If it opens the Prisma Studio, your DB is up and reachable.

### 2. IPv6 vs IPv4 Issue

Some users have found that changing the database URL from to in their environment variables resolves the issue, as Node.js sometimes fails to resolve correctly on some systems (especially on macOS M1/M2).
Example:
Change

to

🙋questionspg-boss failed to start!

kapa.ai•9/17/25, 11:16 AM

Job Configuration

If you do not need background jobs, you can comment out or remove the declarations (like ) in your file. This will prevent pg-boss from starting and can be a temporary workaround if you don't need job functionality.
Several users reported that commenting out the job section allowed their app to start without errors, confirming the issue is isolated to pg-boss and not the database itself.

### 4. Restarting and Cleaning

Sometimes, restarting your machine or running can help, but for this specific issue, the root cause is usually the database connection details or the way pg-boss interacts with the DB after a restart.

### 5. Platform-Specific Issues

The Wasp team has not been able to consistently reproduce this on Linux, but it appears more frequently on macOS, especially with M1/M2 chips. They are investigating further, but no definitive fix is available yet.

---

Summary:

Double-check your database is running and accessible.
Try changing to in your database URL.
If you don't need jobs, comment out the job declarations in your Wasp file.
If the issue persists, it may be a platform-specific bug that the Wasp team is still investigating.

If you can provide logs from and your environment details (OS, Node version, Wasp version), it may help further diagnose the issue. Let me know if you need help with any of these steps!

@kapa.ai I'm trying to deploy on fly but i can't seem to be able to re-attach my db properly

kapa.ai•9/17/25, 11:17 AM

Let me check the knowledge base for you again. One moment!

kapa.ai•9/17/25, 11:17 AM

----------------------
If you're having trouble re-attaching your database when deploying your Wasp app to Fly.io, this is a known issue that can occur if the initial deployment or database attachment fails, or if the app/database names get out of sync. Here are the key points and steps from the knowledge sources:

**Naming Issues & Attachment Problems** If Fly.io generates a unique name for your app (e.g., appending a suffix to avoid name collisions), the Wasp CLI might not correctly attach the database because it expects a certain naming convention. For example, the CLI might look for `open-saas-wispy-fire-4715-server` but the actual app is named differently, causing the attach command to fail. This is a known issue and can prevent re-attachment from working as expected. [CLI deploy fly.io unique name issue](<https://github.com/wasp-lang/wasp/issues/1588>)
**Manual Database Attachment** If the automatic process fails, you can manually attach the database using the Fly CLI. The command generally looks like:```flyctl postgres attach <db-app-name> -a <server-app-name>```Make sure you use the exact names as shown in your Fly.io dashboard.
**Cleaning Up and Retrying** If you encounter persistent issues, you may need to destroy the problematic Fly apps and start over. Use:```flyctl apps destroy <app-name>```This ensures you can re-create and re-attach resources cleanly, as Fly.io does not allow multiple apps with the same name. [Manual deployment docs](<https://wasp-lang.dev/docs/advanced/deployment/manually#set-up-a-flyio-app>)

kapa.ai•9/17/25, 11:17 AM

**.toml Files and Redeployment** If you have existing `fly.toml` files from previous deployments, Wasp may skip some steps or get confused. You can back up or remove these files before retrying, or regenerate them with:```flyctl config save -a <app-name>```[Redeploying after Wasp builds](<https://wasp-lang.dev/docs/advanced/deployment/manually#redeploying-after-wasp-builds>)
**Check Environment Variables** Ensure your environment variables, especially `DATABASE_URL`, are set correctly on Fly. You can set them with:```flyctl secrets set DATABASE_URL=<your-db-url>```

If you continue to have trouble, please provide the exact error message or describe where in the process it fails, as the knowledge sources do not contain a step-by-step fix for every possible scenario. But the above steps should help resolve most re-attachment issues with Fly.io and Wasp.

If the problem is due to a bug in the Wasp CLI's handling of app/database names, you may need to follow the manual steps above until a fix is released.

kapa.ai•9/17/25, 11:20 AM

Let me check the knowledge base for you again. One moment!

kapa.ai•9/17/25, 11:20 AM

----------------------
The error message:

indicates that pg-boss is trying to perform a operation on your database, but the database is in read-only mode. This is a different issue from the common connection errors discussed in the knowledge sources.

From the available knowledge sources, there is no explicit mention of this specific "read-only transaction" error with pg-boss in Wasp deployments. However, based on the context of similar issues:

pg-boss requires write access to the database to manage its job queue (it needs to insert, update, and delete records).
If your database is in read-only mode (for example, if you are connected to a read replica, or your database is in a restricted state on Fly.io), pg-boss will fail to start because it cannot perform the necessary write operations.

What you can do:

Ensure that your database is not in read-only mode and that the user Wasp/pg-boss connects with has full write permissions.
Double-check your and Fly.io database configuration to make sure you are connecting to the primary (writable) instance, not a read replica.

If you are using Fly.io's managed Postgres, make sure you are connecting to the primary database app, not a replica, and that the database is healthy and accepting writes.

Summary:
pg-boss cannot function with a read-only database. You need to ensure your database is writable for Wasp jobs to work. The knowledge sources do not provide a direct solution for this specific error, but this is the logical next step based on how pg-boss operates and the context provided in the sources.

@kapa.ai How can i find the proper database URL ?

kapa.ai•9/17/25, 11:22 AM

Let me check the knowledge base for you again. One moment!

kapa.ai•9/17/25, 11:22 AM

----------------------
To find the proper database URL for your Wasp app—especially when deploying to Fly.io—you need the database name, user, and password. Here’s how you can obtain these details according to the knowledge sources:

**Get the Database Name:**
- Connect to your Fly.io Postgres instance:
- Once connected, list the databases:
- The database name is usually in the format of your server app name with underscores (e.g., )
  See: Github Issue #1464
**Get the Database Password:**
- SSH into your Fly.io Postgres app:
- Then run:
- This will print the password for the user
  See: Github Issue #1464
**Construct the DATABASE_URL:**
- The format is:
- Example:
**If Connecting Locally via Tunnel:**
- Open a tunnel to your production database:
- Then use the above with as the host.

Note:

Make sure nothing else is running on port 5432 locally when you open the tunnel.
Remove the production from your local after you’re done to avoid accidental changes to your production database.

Your server app does not have a DATABASE_URL secret set. Perhaps you need to create or attach your database?

kapa.ai•9/18/25, 8:18 AM

Let me check the knowledge base for you again. One moment!

kapa.ai•9/18/25, 8:18 AM

----------------------
The error message:

means that your Fly.io server app is missing the secret, which is required for your Wasp app to connect to the database.

How to fix:

You need to set the secret for your server app on Fly.io. You can do this with the following command:

Replace with the correct connection string (as described in previous answers), and with the name of your Fly.io server app.

This step is necessary even if you have re-attached the database, as the secret must be present for the server to connect to the database at runtime. The Wasp deployment process expects this secret to be set, and Fly.io uses secrets to securely provide environment variables to your app at runtime Deploying Manually: Environment Variables.

If you need help constructing the correct , see the previous answer or the relevant GitHub issue.

If you continue to see this error after setting the secret, double-check that you are setting it for the correct app and that there are no typos in the secret name.
