Firebase Callable Function + CORS

Question

I\'m trying to call a callable Cloud Function from my app, but I\'m facing CORS issues.

I can\'t enable Cors since I don\'t have access to the request and response

Answer 1

My issue was not with CORS, but with my error handler. Instead of rejecting the promise, I've used throw directly in the catch handler.

catch((err) => {
  throw new functions.https.HttpsError('unknown', err.message, err)
})
