It’s an open bug (although there is a PR under review that may fix it, at least in part). If there was an accepted solution it wouldn’t be an open bug.

Or do you mean you want to test the proposed fix to see how it works for you?

If so, just be warned that this change hasn’t been accepted yet. I would advise having a backup.

You can either grab the patch from here:

https://patch-diff.githubusercontent.com/raw/nextcloud/server/pull/42696.diff

And apply it using a command like patch -p1 42696.diff

Or, since this change is so short, if you haven’t done this before you can edit the file (apps/dav/lib/CalDAV/Status/StatusService.php in yout Nextcloud Server’s installation folder) directly by adjusting the line number(s) show here:

github.com/nextcloud/server

fix(caldav): only call getTimestamp() on actual DateTime data

For some reason the value of `$component['DTSTART'][0]` may not be a `DateTimeI…mmutable`. In the case of #42464, the property is a `Property\ICalendar\Date`, but that extends `Property\ICalendar\DateTime`, so it *should* still give us a `DateTimeImmutable`, but anyway. :shrug: Follow-up to #42619 Closes #42464

Beware it will cause Nextcloud Server to warn about an integrity failure. You’ll likely need to reverse the change before your next upgrade.
