Error 500 when performing a query with drive.file scope

Question

This code runs fine with the scope \"https://www.googleapis.com/auth/drive\"

File folderEntry = drive.files().get(\"XXXXj0_srDPPGUEtHaVYtZFljMEk\").execute();
St         


        

Answer 1

I too get the same error. However this workaround does get all the children of a folder I created, until google fixes the query issue I suppose.

ChildList list = service.children().list(FILEID).execute();

Answer 2

This may be a bit late but... I believe the problem occurs because when you run with the scope https://www.googleapis.com/auth/drive.file you are only allowed to see the files your app has created. However, your query may potentially return metadata that are outside your auth scope.

I had the same problem as well and manage to fix it by adding the DRIVE_METADATA_READONLY scope:

credential = GoogleAccountCredential.usingOAuth2(this, DriveScopes.DRIVE_FILE, **DriveScopes.DRIVE_METADATA_READONLY**);
