Solutions

1. Restore the calendar from trash (Calendar app trash bin or occ trashbin restoration) and re-run
2. Or pick/create a different calendar as the import target
3. occ dav:cleanup to purge deleted calendars, then recreate the URI fresh

$calendar = $calendars[0];
if ($calendar instanceof \OCA\DAV\CalDAV\CalendarImpl && $calendar->isDeleted()) {
    // restore from trash first, or pick another target
}

$isDeletedCalendar = fn ($c): bool =>
    $c instanceof \OCA\DAV\CalDAV\CalendarImpl && $c->isDeleted();

When it happens

Trigger: occ dav:import-calendar alice <uri> ... where the oc_calendars row has deleted_at set because the user deleted it in the Calendar app and it now sits in trash (purged later by occ dav:cleanup).

Common situations: User deleted the calendar and it still appears in legacy listings/PROPFIND caches; import scripts targeting a stale URI; time window before trash purge.
