Research direction

Reproduce the issue with the shown useUser and useFirestoreCollection snippet, then trace how useFirestoreCollection handles an undefined document path. Compare its behavior with null and a nonexistent id; done means the undefined case no longer causes repeated requests and has a defined outcome.

Description

v5

Hello,

the following code results in an infinite loop when user isn't authenticated aka user.data is undefined. Is this expected?

  const user = useUser(undefined, { suspense: true });
  const subscriptions = useFirestoreCollection(
    firestore
      .collection('customers')
      .doc(user.data?.uid)
      .collection('subscriptions')

When something random and non-existent is passed to doc(myId), it throws Missing or insufficient permissions, when null is passed it throws Function CollectionReference.doc() cannot be called with an empty path, however when undefined is passed the code goes into an infinite loop and triggers hundreds of requests per second.
