Server not listening
@kapa.ai my app in development suddenly stopped working yesterday. Both auth and user sign up and API calls. I tried a new install but smart thing. I see in the server logs that it doesn't say that the server is listening like it normqlly does. Any ideas?

Hi @wbjb. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Based on the information provided in the knowledge sources, it seems your issue could be related to port conflicts or network connectivity problems. Here are a few suggestions to troubleshoot:
1. Check if the ports 3000 and 3001 (default for Wasp) are already in use by another process. You can try changing the ports as described in this GitHub issue: Make it easy to use different ports (than 3000 and 3001) during Wasp development.
2. Verify your network settings and firewall rules. Sometimes, firewall settings can prevent the server from listening properly.
3. Review your environment variables, especially
PORT, DATABASE_URL, and JWT_SECRET. Make sure they are correctly set in your .env.server file. This GitHub issue discusses the importance of environment variables: Implement good support for environment variables.
4. Try restarting your development environment completely, including any Docker containers if you're using them.
5. Check if you can run a simple Node.js server on your machine to isolate if it's a Wasp-specific issue or a more general network/system problem.
If none of these steps resolve the issue, you might want to share more detailed logs or error messages from your server. The knowledge sources don't provide enough information about your specific scenario to give a definitive answer, but these general troubleshooting steps should help identify the root cause.

@kapa.ai @Wasp TeamLet me check the knowledge base for you again. One moment! :books:
----------------------
Based on the error message you've provided, it appears that your Wasp application is missing a required environment variable. Specifically, the error states:
This indicates that your server is expecting a Stripe API key to be set in the environment variables, but it's not present. Here's how you can resolve this issue:
1. Create or edit the
.env.server file in the root of your Wasp project. This file is used for setting server-side environment variables during development, as mentioned in the Wasp documentation on environment variables.
2. Add the following line to your .env.server file:
Replace your_stripe_api_key_here with your actual Stripe API key.
3. Make sure not to commit this file to version control, as it contains sensitive information. The .env.server file should already be in your .gitignore by default.
4. After adding the environment variable, try restarting your Wasp application using wasp start.
If you don't have a Stripe API key or aren't intending to use Stripe in your application, you may need to review your code and remove or comment out any Stripe-related functionality.
Remember, as mentioned in the Wasp documentation on deploying manually, when you deploy your application to production, you'll need to set this environment variable in your production environment as well.
If you continue to face issues after setting the environment variable, please provide more details about your application setup and any Stripe-related code you might have.

Perhaps try again in 15mins?@kapa.ai thats not it. It was working perfectly fine before the server stopped responding and no changes were made to that file. COuld it be a problem with my machine?
Let me check the knowledge base for you again. One moment! :books:
----------------------
Based on the information provided in the knowledge sources and our previous conversation, it's possible that the issue could indeed be related to your machine or local environment rather than the Wasp application itself. Here are a few possibilities to consider:
1. Background processes: As mentioned in the Discord support thread about pg-boss connection issues, there might be some background processes or resources not being properly freed up. This could cause issues when restarting the application.
2. Port conflicts: Another possibility is that there might be a port conflict. Even though you haven't made changes, another application might have started using the required ports.
3. Database connection: If your application uses a database, there might be an issue with the database connection. The Discord support thread about pg-boss mentions issues with database connections that persisted even after restarting the database.
4. System resources: If your system is low on resources (memory, CPU), it might affect the application's ability to start properly.
To troubleshoot these potential machine-related issues, you could try the following:
1. Restart your computer completely. This can help clear any lingering processes or port conflicts.
2. Check if the required ports (usually 3000 and 3001) are free using a command like
lsof -i :3000 and lsof -i :3001 (on Unix-based systems).
3. Try running wasp clean before starting your application again. This will clear out the .wasp directory and might resolve any cached issues.
4. Check your system's resource usage to ensure you have enough free memory and CPU.
5. If you're using a local database, try restarting it manually.
If none of these steps resolve the issue, it would be helpful to gather more detailed logs or error messages from your server. The current knowledge sources don't provide enough specific information about your particular setup to give a definitive answer, but these troubleshooting steps should help identify if the problem is indeed related to your machine.

Perhaps try again in 15mins?@kapa.ai I was able to resolve this. It appears it was my machine. I shut it down completely instead of just restarting and that seems to have reset whatever was going on. I had tried that before. But whatever. Pg boss is now working and it's listening on the correct port
Let me check the knowledge base for you again. One moment! :books:
----------------------
I'm glad to hear that you were able to resolve the issue! Your experience aligns with what we discussed earlier about potential machine-related problems. Shutting down your computer completely can indeed help resolve various issues that a simple restart might not catch. This approach can clear up lingering processes, free up system resources, and reset network configurations.
Your solution of performing a full shutdown instead of just restarting is a good troubleshooting step to keep in mind for future reference. It's especially useful for resolving issues related to background processes, port conflicts, or resource allocation problems.
It's great that pg-boss is now working correctly and the server is listening on the proper port. This outcome suggests that there might have been some persistent process or system state that was interfering with your Wasp application's ability to start correctly.
For future reference, if you encounter similar issues, remember that a full shutdown can be an effective troubleshooting step, especially when dealing with stubborn problems that persist after normal restarts.
Thank you for sharing the resolution. It's valuable information that might help other Wasp users who encounter similar issues in the future.

Hey @wbjb
Very strange, but glad you got it working!
Did you figure out what caused it in the end?
@sodic No idea. My working theory is that something was up with my machine where the ports wouldn't open. I had tried several restarts and a new complete shutdowns and I ran the fuser kill a few times too. In the end, I did another complete shutdown and walked away for a bit and it worked. The worst part of all of this was that I was trouble shooting some problems with API calls and I was pulling my hair out until I realized I wasn't even communicating with the server.
Ah yes, I know the feeling
Makes you want to throw your computer out of the window
Glad it's all over now 🙂

I apologize for the recurring issue you're experiencing. Based on the error message you've provided, it seems that an environment variable is undefined. However, the specific variable name is not shown in the error output. Let's try to troubleshoot this issue:
1. Check your
.env.server file:
Make sure you have a .env.server file in the root directory of your Wasp project. This file should contain all the necessary environment variables for the server-side of your application.
2. Review required environment variables:
The OpenSaaS template typically requires several environment variables. Check if you have all of these set in your .env.server file:
- DATABASE_URL
- JWT_SECRET
- STRIPE_SECRET_KEY
- STRIPE_WEBHOOK_SECRET
- SENDGRID_API_KEY
- WASP_WEB_CLIENT_URL
Make sure none of these are empty or undefined.
3. Validate environment variables:
The error is occurring in the validate-env.mjs script. You might want to check this script (located in the scripts folder) to see which specific variable it's failing on.
4. Clean and rebuild:
Try running wasp clean and then wasp start again. This will clear any cached builds and start fresh.
5. Check for spaces or special characters:
Ensure there are no trailing spaces or special characters in your .env.server file that might be causing issues.
6. Use the latest Wasp version:
Make sure you're using the latest version of Wasp. You can check with wasp version and update if necessary.
If the issue persists after trying these steps, it would be helpful to see the contents of your .env.server file (with sensitive information redacted) and the validate-env.mjs script to provide more specific guidance.
Remember, as mentioned in the Wasp documentation on environment variables, environment variables are crucial for the proper functioning of your Wasp application, especially when using features like authentication, external APIs, or databases.

Based on the error message you've provided, it's clear that the issue is related to a missing environment variable. Specifically, the STRIPE_API_KEY is undefined. Let's address this issue:
1. First, make sure you have a .env.server file in the root directory of your Wasp project. If it doesn't exist, create one.
2. In your .env.server file, add the following line:
Replace your_stripe_secret_key_here with your actual Stripe secret key. You can find this in your Stripe dashboard.
3. Make sure there are no spaces before or after the equals sign, and that the variable name is exactly STRIPE_API_KEY.
4. After adding or updating this environment variable, try restarting your Wasp application using wasp start.
It's important to note that, as mentioned in the Wasp documentation on environment variables, environment variables prefixed with REACT_APP_ are for client-side use, while others (like STRIPE_API_KEY) are for server-side use.
If you're not actually using Stripe in your application, you might need to remove or comment out any Stripe-related code. The error suggests that there's Stripe-related code in your project (specifically in /home/brad/haystack30/app/src/payment/stripe/stripeClient.ts).
Regarding the warning about CommonJS and ES modules, this is an experimental feature warning and shouldn't affect the functionality of your app. However, if you want to suppress this warning, you can run your app with the --no-warnings flag.
If you continue to face issues after setting the environment variable, please review your Stripe-related code and ensure that you're using the correct variable names throughout your application.

----------------------
I'm glad to hear that you've resolved the issue! You're not an idiot at all - it's a common oversight that can happen to anyone, especially when setting up a new installation.
As you've discovered, copying the environment file is a crucial step in setting up a Wasp project. For future reference and for others who might encounter a similar situation, here's a quick reminder of the process:
1. In the root of your Wasp project, there should be a
.env.server.example file.
2. You need to copy this file and rename it to .env.server.
3. You can do this easily in the terminal with the command:
4. After copying, make sure to fill in the actual values for your environment variables in the .env.server file.
This step is mentioned in the Wasp documentation on environment variables, and it's an important part of the setup process.
Thank you for sharing the resolution. It's a good reminder for all Wasp users about the importance of properly setting up environment variables when starting a new project or installation.
