Try adding access_type with the value offline to your auth request.

I had a very similar error to this not 2 days ago and this fixed the problem.

Also, just to confirm the clientID value should be similar to @developer.gserviceaccount.com They basically expect the email_address value from the console api credentials - not the client_id
