Google Meet is already connected for this user.

Error message

Google Meet is already connected for this user.

What it means

Thrown by GoogleMeetService.connectGoogleMeetToUser when conferencingRepository.findGoogleMeet(userId) returns an existing credential — the user already has a google_meet credential row. Returns HTTP 400 via BadRequestException. Connecting again would create a duplicate; the existing credential is reused. Reached via POST /v2/conferencing/google_meet/connect → connectUserNonOauthApp.

Solutions

  1. Before calling connect, check GET /v2/conferencing — if google_meet is listed, skip the connect call.
  2. Disable the connect button immediately on click (debounce) to prevent double-submit.
  3. Treat this 400 as success-equivalent in the client (idempotent connect) since the end state — Google Meet connected — is achieved.
  4. If you want true idempotency, switch the service to upsert instead of throw on duplicate.

Example fix

// before
await api.connectConferencing('google_meet');

// after
const installed = await api.listConferencingApps();
if (!installed.data.some(a => a.slug === 'google_meet')) {
  await api.connectConferencing('google_meet');
} else {
  showToast('Google Meet is already connected.');
}
Defensive patterns

Strategy: validation

Validate before calling

async function googleMeetAlreadyConnected(conferencingRepository: ConferencingRepository, userId: number): Promise<boolean> {
  return Boolean(await conferencingRepository.findGoogleMeet(userId));
}

if (await googleMeetAlreadyConnected(conferencingRepository, userId)) {
  return { status: 'already_connected', app: 'google_meet' };
}

Type guard

function isGoogleMeetCredential<T extends { type: string }>(c: T | null): c is T & { type: 'google_meet' } {
  return c !== null && c.type === 'google_meet';
}

Try / catch

try {
  await googleMeetService.connectGoogleMeetToUser(userId);
} catch (e) {
  if (e instanceof BadRequestException && /already connected/i.test(e.message)) {
    // idempotent — treat as success
    return { status: 'already_connected' };
  }
  throw e;
}

Prevention

When it happens

Trigger: User clicks 'Connect Google Meet' a second time; the frontend did not refresh its connected-apps state after the first connect; a retry fired because the first response was slow.

Common situations: UI button stays enabled after connect; double-submit (no debounce); race between two connect clicks; the connect succeeded but the response was lost and the client retried.
