No SelectedCalendar found.

Error message

No SelectedCalendar found.

What it means

NotFoundException (HTTP 404) thrown by SelectedCalendarsService when deleting a user selected calendar and the underlying repository reports NO_SELECTED_CALENDAR_FOUND. The repository's removeUserSelectedCalendar raises this when no row matches the (userId, integration, externalId) tuple, and the service translates the string message into a 404.

Solutions

1. Before deleting, confirm the calendar still appears in GET /v2/selected-calendars for the user.
2. Treat a 404 on delete as a success if your goal is simply 'ensure it is gone' (idempotent delete).
3. Verify the integration key and externalId exactly match the values returned by the list endpoint.

Example fix

// before
await api.delete(`/selected-calendars/${integration}/${externalId}`);
// after — idempotent removal
try {
  await api.delete(`/selected-calendars/${integration}/${externalId}`);
} catch (e) {
  if (e.status !== 404) throw e; // already gone is fine
}

async function removeCalendarIdempotent(userId: number, integration: string, externalId: string) {
  const list = await api.get('/selected-calendars', { params: { userId } });
  const exists = list.some((c: { integration: string; externalId: string }) =>
    c.integration === integration && c.externalId === externalId);
  if (!exists) return; // already gone
  return api.delete(`/selected-calendars/${integration}/${externalId}`);
}

const isExistingCalendar = (list: { integration: string; externalId: string }[], integration: string, externalId: string): boolean =>
  list.some(c => c.integration === integration && c.externalId === externalId);

try { await api.delete(`/selected-calendars/${integration}/${externalId}`); }
catch (e) { if (e.status !== 404) throw e; /* already removed — ok */ }

When it happens

Trigger: DELETE /v2/selected-calendars with an integration+externalId pair that the user never connected, or already removed; a sync process trying to remove a calendar that was deleted by another client in the meantime.

Common situations: Stale UI list still showing a calendar the user disconnected elsewhere; webhook firing twice for the same calendar removal; integration name mismatch (e.g. 'google_calendar' vs 'google') or externalId drift after re-auth.
