Reason [internalError] Domain [global]]

I am getting tones of these very common errors in my solution while accessing the Google Drive service via the SDK.

Can anyone point out why these errors are happening? For the most part, the solution works, but then randomly these exceptions will only appear!

Maybe if I can support email directly, that would be great :)

Also, I have received over 600 instances of this exception in the last hour and should really solve it!
