Getting Server Rejected error when upload using Google Picker, Oauth2

Question

We are trying to use google.picker to have our users upload files to our drive account (i.e., the user is not required to have a Google account to upload).

We're trying to use regular Google accounts as application-owned accounts and got our AUTH_TOKEN using OAuth2 and set it using .setOAuthToken(AUTH_TOKEN) . We followed everything described in the docs.

However, when uploading, we got a Server Rejected error. The call to https://docs.google.com/upload/resumableupload?authuser=undefined returned:

{"errorMessage":{"reason":"REQUEST_REJECTED","additionalInfo":{"uploader_service.GoogleRupioAdditionalInfo":{"completionInfo":{"status":"REJECTED"},"requestRejectedInfo":{"reasonDescription":"agent_rejected"}}},"upload_id":"AEnB2Ur64Gb0JDCk_8mg5EhpdcaqL82wBQHumHjcGvDqYibtksmUzhfhBolsmBFzRuvQPRyi43SYfactJZvIWYrQ6xAqzu3L9g"}}

We know we cannot use service accounts since the picker doesn't support it.

Do we miss something in getting the AUTH_TOKEN? Do we need to something in the console?

Answer 1

Give us a little more code, or check the call to gapi.auth.authorize()

1. Check that you are using the correct scope to obtain the OAuth token.
   • Scope should be https://www.googleapis.com/auth/drive
2. Double-Check the scope declaration:
   • https://developers.google.com/accounts/docs/OAuth2Login#sendauthrequest

3. Check the call to gapi.auth.authorize()

   window.gapi.auth.authorize( {      'client_id': clientId,      'scope': scope,      'immediate': false }, handleAuthResult); 

   from: https://developers.google.com/picker/docs/#hiworld

Without an actual code sample, it is very difficult to say exactly what is going on. Most likely it is the auth token colection. However, it may also be something as simple as not defining a google User (clientID) which in turn impacts the gapi.auth.authorize() call.
