Today I started to get this error upon adding new events to calendar:
Fatal error: Uncaught exception 'apiServiceException' with message
'Error calling POST https://www.googleapis.com/calendar/v3/

It worked perfectly till now and I didn’t change anything in code.
Well, they released new version and that what apparently caused errors. Got the newest version now and it works great once again.
