Issue

Upgraded to the release candidate and using the following collection subscription:

collectionData(collection(firestore, `users/${u.uid}/devices`), {
 idField: 'id',
})

Error

ERROR FirebaseError: Expected type '_Query', but it was: a custom _CollectionReference object

Analysis

Not sure how to provide more detail on this, but it seems to be during a cast to Query in the onSnapshot handler.
