Another person is having trouble getting GCal to work. I updated the documentation on creating credentials because google changed their UI layout and sequence - so that should help.
The bigger problem though is that vera seems to have broken certain behavior with their latest upgrade. The result is that the CalendarID’s and Credential file names are not being passed in. For users with existing plugins - they still work but will likely fail if the user tries to change a CalendarID or Credential FileName
I will have to follow up with vera development.
