${appSlug} not connected.

Error message

${appSlug} not connected.

What it means

Thrown by ConferencingService.checkAppIsValidAndConnected when the slug is valid but no connected credential with an app location is found for the user. Returns HTTP 400. Used by disconnectConferencingApp (cannot disconnect what is not connected) and setDefaultConferencingApp (cannot default to a non-connected app, except cal_video which is global).

Solutions

1. Refresh the installed-apps list via GET /v2/conferencing before offering disconnect/set-default actions.
2. If the user expects it connected, have them reconnect via the OAuth flow.
3. For setDefaultConferencingApp, cal_video bypasses this check — use cal_video if no app is connected.
4. Investigate any credential rows missing appData.location as a data-integrity bug.

Example fix

// before
await api.setDefaultConferencing('zoom');

// after
const installed = await api.listConferencingApps();
const slugs = installed.data.map(a => a.slug);
if (!slugs.includes('zoom')) {
  showToast('Connect Zoom first.'); return;
}
await api.setDefaultConferencing('zoom');

async function isAppConnected(conferencingService: ConferencingService, user: UserWithProfile, appSlug: string): Promise<boolean> {
  try {
    await conferencingService.checkAppIsValidAndConnected(user, appSlug);
    return true;
  } catch (e) {
    if (e instanceof BadRequestException && /not connected/.test(e.message)) return false;
    throw e;
  }
}

if (!(await isAppConnected(conferencingService, user, app))) {
  return { code: 'app_not_connected', app };
}

interface InstalledApp { slug: string; credential?: { id: number } }

function isConnectedApp<T extends InstalledApp>(apps: T[], slug: string): apps is (T & { credential: { id: number } })[] {
  return apps.some(a => a.slug === slug && Boolean(a.credential));
}

try {
  await conferencingService.setDefaultConferencingApp(user, app);
} catch (e) {
  if (e instanceof BadRequestException && /not connected/.test(e.message)) {
    return res.status(400).json({ code: 'app_not_connected', app });
  }
  throw e;
}

When it happens

Trigger: Calling DELETE /v2/conferencing/zoom/disconnect when the user never connected Zoom, or connected then deleted it; calling POST /v2/conferencing/zoom/default without a Zoom credential; the credential exists but its appData.location is missing (incomplete install).

Common situations: Stale UI showing an app as connected; user connected in a different account/tenant; app-store credential row missing location metadata after a partial install.
