How do I change the schema of convex auth or use createOrUpdateUser callbacks from convexAuth?

[tawny wigeon]

I tried following the documentation on how to use createOrUpdateUser to create a custom user creation, but for some reason I cannot make it work and it seems the callback doesn't even called. I added console.log inside the createOrUpdateUser callback and it doesn't show up. Is there more detailed or comprehensive guide on how to use it?

export const { auth, signIn, signOut, store } = convexAuth({
  providers: [
    GitHub
  ],
  callbacks: {
    async createOrUpdateUser(ctx, args) {
      console.log("CREATE OR UPDATE USER CALLBACK")

      if (args.existingUserId) {
        // Optionally merge updated fields into the existing user object here
        return args.existingUserId;
      }

      // Implement your own account linking logic:
      const existingUser = await getUserByEmail(ctx, { email: args.profile.email as string });
      if (existingUser) return existingUser._id;

      // Implement your own user creation:
      return ctx.db.insert("users", {
        /* ... */
      });
    }
  }
})

Hi @tawny wigeon. 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, I can offer some insights and suggestions regarding your question about using the createOrUpdateUser callback in Convex Auth.

1. Callback not being called:
   If your createOrUpdateUser callback is not being called, it's possible that there might be an issue with how it's implemented or how the authentication flow is set up. Unfortunately, the knowledge sources don't provide a specific reason why the callback might not be triggered in your case.

2. Logging:
   You're on the right track by adding console.log statements to debug. However, to get more detailed logging, you can try setting the AUTH_LOG_LEVEL environment variable to DEBUG in your Convex environment. This should provide more information about what's happening during the authentication process, as mentioned in this Discord thread (https://discord.com/channels/1019350475847499849/1280847812795301989).

3. Callback implementation:
   Your implementation of createOrUpdateUser looks generally correct based on the examples provided in the Convex Auth documentation (https://labs.convex.dev/auth/advanced#controlling-user-creation-and-account-linking-behavior). However, make sure that your getUserByEmail function is correctly implemented and doesn't throw any errors.

4. Type annotations:
   To ensure proper typing and avoid potential issues, you can add type annotations to the callback parameters. This was suggested in a Discord thread (https://discord.com/channels/1019350475847499849/1281602754950987857) as a workaround for some typing issues:

   async createOrUpdateUser(ctx: MutationCtx, args) {
     // ... your implementation
   }
   

   Make sure to import MutationCtx from your _generated/server file.

5. Alternative approach:
   If you're having trouble with createOrUpdateUser, you could try using the afterUserCreatedOrUpdated callback instead. This callback is called after the user is created or updated, and it might be easier to work with in some cases. You can find more information about it in the Convex Auth documentation (https://labs.convex.dev/auth/advanced#writing-additional-data-during-authentication).

6. Checking for errors:
   Make sure to check your server logs for any error messages that might indicate why the callback isn't being called or if there are any issues with your implementation.

If you're still having trouble after trying these suggestions, it might be worth reaching out to the Convex support team or filing an issue on their GitHub repository, as there might be a bug or an undocumented limitation.

Remember that customizing user creation and authentication flows can be complex, and it's important to thoroughly test your implementation to ensure it works as expected and handles all possible scenarios.

@tawny wigeon Kapa.ai is still learning and improving, please let me know how I did by reacting below.

@snow current I tried the suggested method, unfortunately I still can't figure out the problem. the debug shows error but it seems unrelated to the createOrUpdateUser callback function.

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

I understand you're still facing issues with the createOrUpdateUser callback function, and the debug logs are showing an error that seems unrelated. Let's try to troubleshoot this further based on the information available in our knowledge sources.

1. Debug Logs:
   It's good that you've enabled debug logging as suggested. Even if the error seems unrelated, it might provide clues about what's happening during the authentication process. Could you share the specific error message you're seeing? This would help in understanding the issue better.

2. Checking the Implementation:
   Make sure that your createOrUpdateUser function is correctly implemented within the convexAuth configuration. The Discord thread (https://discord.com/channels/1019350475847499849/1280847812795301989) mentions that this function should be placed in the callbacks object:

   export const { auth, signIn, signOut, store } = convexAuth({
     providers: [GitHub],
     callbacks: {
       async createOrUpdateUser(ctx, args) {
         // Your implementation here
       },
     },
   });
   

3. Alternative Approach:
   If you're still having trouble with createOrUpdateUser, you might want to try using the afterUserCreatedOrUpdated callback instead. This was suggested in another Discord thread (https://discord.com/channels/1019350475847499849/1303356205560758323) as a potential workaround:

   callbacks: {
     async afterUserCreatedOrUpdated(ctx: MutationCtx, { userId }) {
       // Your custom logic here
     },
   }
   

However, be aware that this approach has its limitations, as mentioned in the same thread: "UPDATE: afterUserCreatedOrUpdated was not a good approach because the authSession gets set after this callback so there would be a mismatch with the authAccount and the authSession pointing to different userIds after my mutations."

4. Checking Auth Tables:
   Ensure that your schema includes the necessary auth tables. As mentioned in a Discord thread (https://discord.com/channels/1019350475847499849/1265470621102510160), you should have spread the authTables object in your schema. If you haven't done this, it could cause issues with user creation.

5. Verbose Logging:
   If you haven't already, try enabling verbose logging on both the client and server side. This can provide more detailed information about what's happening during the authentication process. You can find instructions on how to do this in the Convex debugging documentation (https://labs.convex.dev/auth/debugging).

6. Check for Recent Updates:
   Make sure you're using the latest version of Convex Auth. A Discord thread (https://discord.com/channels/1019350475847499849/1289247646766334084) mentioned that upgrading to a newer version (in their case, from 0.0.67 to 0.0.71) solved some issues.

If you're still encountering problems after trying these suggestions, it might be helpful to share more details about the specific error you're seeing and any relevant parts of your implementation. The Convex team or community might be able to provide more targeted assistance with more information.
