Let's take a more fundamental approach to fix the "Unknown error" when accessing the Google sign-in route.
I've completely revised the authentication approach to address the "Unknown error" when accessing the Google sign-in route. Here are the key changes:
Simplified NextAuth Configuration:
Created a Custom Login Page:
/login page that doesn't rely on NextAuth's built-in pagesUpdated Middleware:
Added Environment Variable Testing:
/api/test-env to verify environment variablesCreated a Direct Google Sign-in Route:
/api/google-signin that directly handles Google OAuthTo troubleshoot the issue:
/api/test-env to verify your environment variables are correctly set/login page instead of the NextAuth sign-in pageIf you're still experiencing issues, it might be related to how the environment variables are being accessed or a compatibility issue with NextAuth and your hosting environment. In that case, you might want to consider a simpler authentication approach or a different authentication provider.
Please make sure to add the following environment variable to your project:
Great! Adding the NEXTAUTH_URL environment variable is an important step. This variable tells NextAuth.js the base URL of your application, which is crucial for proper callback handling and redirect URLs.
Now that you have all the required environment variables (GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, AUTH_SECRET, and NEXTAUTH_URL), let's test the authentication flow:
Try the Custom Login Page First:
/login in your applicationCheck Environment Variables:
/api/test-env to verify all environment variables are correctly settrue in the JSON responseVerify Google OAuth Configuration:
Make sure your Google OAuth credentials have the correct redirect URI:
https://your-domain.com/api/auth/callback/googlehttp://localhost:3000/api/auth/callback/googleIf you're still experiencing the "Unknown error":
CORS Issues:
Redirect URI Mismatch:
Cookie Issues:
secure: false in the NextAuth configurationTry a Different Browser:
If you continue to face issues with NextAuth, you might want to consider a simpler approach:
/api/google-signin)Would you like me to provide more details on any of these approaches or help troubleshoot specific errors you're seeing?
The code returns the following error:
