I have identified the problematic property:

  "outOfOfficeProperties": {
    "autoDeclineMode": "declineAllConflictingInvitations",
    "declineMessage": "Out sick, but available for important or urgent matter "
  }

Import works again after removing it.

Confirming the removal of outOfOfficeProperties (via delete event.outOfOfficeProperties) does fix the problem. Thanks!

I have forwarded this to the engineering team. Another request failing with 400 but not having the outOfOfficeProperties field would be helpful. Thank you.

Our script also broke for syncing individual time off to a shared team calendar. In my case I had to delete the outOfOfficeProperties attribute and also change the eventType to default as the outOfOffice eventType is not supported in shared calendars.

function importEvent(username, event) {
  event.summary = '[' + username + '] ' + event.summary;
  event.organizer = {
    id: TEAM_CALENDAR_ID,
  };
  event.attendees = [];

  // remove outOfOfficeProperties to support importing outOfOffice events
  // see https://issuetracker.google.com/issues/313935022?pli=1
  delete(event.outOfOfficeProperties);

  // switch event type to default, cannot create `outOfOffice` events in shared calendars
  event.eventType = 'default';

  console.log('Importing: %s', event.summary);

  try {
    Calendar.Events.import(event, TEAM_CALENDAR_ID);
  } catch (e) {
    console.error('Error attempting to import event: %s. Skipping.',
        e.toString());
  }
}

I can confirm, I also had to set

event.eventType = 'default';

to make it work again.

True, looks like the new error started at midday December 15th.

Why on Earth is there try/catch instead of sending error alerts (when run via triggers) like a normal script...?

My solution is therefore a new variable called TEMPORARY_FIX and checking for it inside the relevant function (but note I only do this for eventType outOfOffice):

let TEMPORARY_FIX = true;
...
function importEvent(username, event) {
...
  try {commonmark.org
    if (typeof TEMPORARY_FIX !== 'undefined' && TEMPORARY_FIX && event.eventType == 'outOfOffice') {
          delete event.outOfOfficeProperties;
          event.eventType = 'default';
    }
    Calendar.Events.import(event, TEAM_CALENDAR_ID);
  } catch (e) {

Can confirm that the following worked for me prior to importing events on the shared calendar:

delete event.outOfOfficeProperties;
 event.eventType = 'default';
