Error message

Unhandled values

What it means

Thrown by the example credential-sync getToken endpoint when req.body.appSlug is neither 'google-calendar' nor 'zoom'. This is example/demo code showing how to build a credential sync server; it only implements two providers. The error is caught and returned as a 500 JSON body.

Solutions

1. Add a branch for the new appSlug with its token-generation function in getToken.ts and the shared integrations lib.
2. Ensure the request body includes appSlug matching one of the supported values.
3. Copy this pattern into a real server and implement the providers you actually use.

Example fix

// before
if (appSlug === 'google-calendar') { ... }
else if (appSlug === 'zoom') { ... }
else { throw new Error('Unhandled values'); }
// after
const generators: Record<string, () => Promise<string>> = {
  'google-calendar': generateGoogleCalendarAccessToken,
  'zoom': generateZoomAccessToken,
  'microsoft-teams': generateTeamsAccessToken,
};
const gen = generators[appSlug];
if (!gen) throw new Error(`Unhandled appSlug: ${appSlug}`);
accessToken = await gen();

const supported = ['google-calendar', 'zoom'];
if (!supported.includes(appSlug)) {
  return res.status(400).json({ error: `Unsupported appSlug '${appSlug}'. Supported: ${supported.join(', ')}` });
}

const SUPPORTED_SLUGS = ['google-calendar', 'zoom'] as const;
type SupportedSlug = typeof SUPPORTED_SLUGS[number];
function isSupportedSlug(s: unknown): s is SupportedSlug {
  return typeof s === 'string' && (SUPPORTED_SLUGS as readonly string[]).includes(s);
}

null

When it happens

Trigger: POST to /api/getToken in the example credential-sync app with appSlug set to any value other than 'google-calendar' or 'zoom' (e.g. 'outlook', 'stripe', or undefined).

Common situations: Extending credential sync to a new provider without adding a branch; appSlug missing from the request body; typo in the slug; Cal.com requesting a token for an app the example server does not yet support.
