Error message

Invalid app, available apps are: 

What it means

Thrown by ConferencingService.checkAppIsValidAndConnected when appSlug is not in the CONFERENCING_APPS array. This is the pre-flight validation used by disconnectConferencingApp and setDefaultConferencingApp. Returns HTTP 400. Like error 94 the message string ends mid-sentence and the full list is in the error-cause argument.

Solutions

1. Source the slug from the documented CONFERENCING_APPS constant or the GET /v2/conferencing list response.
2. Filter client-side dropdowns to only supported slugs.
3. Read the error-cause argument to surface the actual accepted list to the user.
4. Validate the slug against a known enum before issuing disconnect/default requests.

Example fix

// before
await api.disconnectConferencing(userInputSlug);

// after
import { CONFERENCING_APPS } from '@calcom/platform-constants';
if (!CONFERENCING_APPS.includes(userInputSlug)) {
  throw new UserError(`Unsupported conferencing app. Supported: ${CONFERENCING_APPS.join(', ')}`);
}
await api.disconnectConferencing(userInputSlug);

import { CONFERENCING_APPS } from '@calcom/platform-constants';

function validateConferencingAppSlug(slug: string): void {
  if (!CONFERENCING_APPS.includes(slug)) {
    throw new Error(`${slug} is not a supported conferencing app. Valid: ${CONFERENCING_APPS.join(', ')}`);
  }
}

validateConferencingAppSlug(req.params.app);

import { CONFERENCING_APPS } from '@calcom/platform-constants';

function isConferencingApp(slug: string): slug is typeof CONFERENCING_APPS[number] {
  return CONFERENCING_APPS.includes(slug);
}

try {
  await conferencingService.disconnectConferencingApp(user, app);
} catch (e) {
  if (e instanceof BadRequestException && /available apps are/.test(e.message)) {
    return res.status(400).json({ code: 'invalid_app', supported: CONFERENCING_APPS });
  }
  throw e;
}

When it happens

Trigger: Calling DELETE /v2/conferencing/{app}/disconnect or POST /v2/conferencing/{app}/default with an app slug not in CONFERENCING_APPS (e.g. 'webex', 'whereby', or a typo like 'daily').

Common situations: Client built before a slug rename; user typed a slug; integration lists third-party conferencing apps not supported by the platform API.
