It's probably an issue with the event details like title or text (possibly sanitization related like you mentioned).
I think I get that error once in a while, but in general, the script should still work and the Google Calendar API hasn't changed.
API changes?
Script is broken now, 400 Bad Request from calendar.google.com Maybe they changed the Calendar API? Or the text sanitization failed?
