Google Calendar integration - entities suddenly unavailable

Configuration
1

I’m unsure where to go from here. One day last week, my calendar entities (there are three) started to drop off after working for over a year. I deleted the integration and re-installed, first without deleting the auth keys and then with deleting. I went back through the OAuth setup in my Google account. The API page is showing requests from this morning.

I’ve deleted the .token file from the config folder; my understanding is that it’s no longer needed anyway.

The calendar API is enabled in the Google account. Here’s a log entry for the three calendars from a few minutes ago (XXXXX are calendar names):

Any ideas on why this might be happening?

Nope, but as of this afternoon my personal calendar for Google is also reporting this error. Other shared calendars coming in through the same account work fine, it looks like it chokes on one of the upcoming appointments.

So, I lost one, and then two… the third remained working until I removed the integration to try to fix the other two. Now all three are gone. So my recommendation is, maybe don’t touch it until we find a fix for the broken ones.

I have been told that there will be a fix in the next upgrade.

Any ETA on when that will be pushed?

Also have this error. Anyone knows when we can expect an update? Really annoying - all family events suddenly not triggering from calendar…
