Troubleshooting DrEdit Python app on GAE: HTTP 403 error when accessing files

Hey everyone,

I’m having trouble with the DrEdit sample app for Python on Google App Engine. The app starts up fine, but I’m hitting a roadblock when trying to open or save files. It keeps throwing an HTTP 403 error saying “Access Not Configured”.

I’ve double-checked my setup:

  • Added client_id and client_secret to the client.json file
  • Tried using both Drive SDK and web application client IDs
  • Set the OAuth Client ID in Google Drive SDK settings

But no luck so far. The app just won’t play nice with file operations. Any ideas what I might be missing or doing wrong? I’m pretty stumped at this point.

Has anyone else run into this issue before? Any tips or tricks would be super helpful. Thanks in advance!

I encountered a similar issue when working with the DrEdit sample app. One thing that helped me was double-checking the scopes in my OAuth consent screen configuration. Make sure you have the necessary Drive API scopes properly set up, especially ‘https://www.googleapis.com/auth/drive.file’ for file-specific operations.

Also, verify that your service account has the correct permissions. Sometimes, the 403 error can occur if the service account doesn’t have the right access levels. You might need to grant it additional roles in the IAM settings.

Lastly, try clearing your browser cache and cookies, then reauthorize the app. OAuth tokens can sometimes get stale or corrupted, leading to unexpected authorization errors. A fresh start might just do the trick.

Hope this helps you troubleshoot the issue. Let us know if you make any progress!

Have you checked your OAuth 2.0 configuration? Sometimes these 403 errors occur due to mismatched redirect URIs. Ensure your authorized redirect URIs in the Google Cloud Console match exactly with what’s in your app’s configuration. Also, verify you’re using the correct OAuth 2.0 flow for a web server application.

Another potential issue could be related to the app’s credentials. Try creating a new set of credentials and updating your client.json file. Sometimes, regenerating these can resolve unexpected authorization problems.

If you’re still stuck, enable more detailed logging in your GAE app. This might provide additional insights into where exactly the authorization is failing. You can do this by adjusting the logging level in your app.yaml file.

hey there! ive run into this before. make sure u’ve enabled the Drive API in ur Google Cloud Console. go to APIs & Services, search for Drive API and enable it. that fixed it for me. good luck!
