Solutions

1. Invalidate the connected-calendars cache for the user and retry check.
2. Re-run the save callback so createAndLinkCalendarEntry links the primary calendar.
3. Confirm a SelectedCalendars row exists for the google primary calendar externalId + credentialId.

Example fix

// before: check right after save returns 401 (stale cache / not linked)
await api.get('/v2/calendars/google_calendar/check'); // 401

// after: clear cache server-side then re-check
calendarsCacheService.deleteConnectedAndDestinationCalendarsCache(userId);
await api.get('/v2/calendars/google_calendar/check'); // 200 once linked

// Confirm the google calendar is linked (after cache refresh) before check
const { data } = await api.get('/v2/calendars', { params: { ensureDefaultSelectedCalendars: true } });
const linked = data.connectedCalendars.some(c => c.integration?.type === 'google_calendar');
if (!linked) throw new Error('Google calendar did not link — re-run save');

function hasConnectedGoogle(list) {
  return Array.isArray(list) && list.some(c => c?.integration?.type === 'google_calendar');
}

try {
  await api.get('/v2/calendars/google_calendar/check');
} catch (e) {
  if (e.response?.status === 401 && /not connected/i.test(e.response?.data?.message)) {
    // re-run save callback to link the primary calendar, then retry once
    await reRunGoogleSaveCallback();
    return api.get('/v2/calendars/google_calendar/check');
  }
  throw e;
}

When it happens

Trigger: OAuth completed but the primary calendar was never linked (saveCalendarCredentialsAndRedirect didn't reach createAndLinkCalendarEntry); cache stale; selectedCalendars row missing for the primary calendar id.

Common situations: Save flow returned early (no primaryCal.id, or alreadyExistingSelectedCalendar branch); cache not invalidated after connect; race between save and check.
