# Issue Upgraded to the release candidate and using the following collection subscription: ``` typescript 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.
