TypeError: v1.isEqual is not a function

I’m getting TypeError: v1.isEqual is not a function when I use the useDocument hook

const profileRef = firebase
    .firestore()
    .collection('users')
    .doc(user.uid)

const { error, loading, value } = useDocument(profileRef)

 "react": "16.8.3",
 "react-firebase-hooks": "^1.1.0",
 "react-native": "0.59.1",
 "react-native-firebase": "^5.2.3",

Any ideas?

For those who came across this error when not using react-native-firebase, I recently received this error when i supplied a string instead of a ref to useList()

The following snippet produced the error:

  const [snapshots, loading, error] = useList("/leaderboard");

it is fixed by replacing it with a ref like so:

  const [snapshots, loading, error] = useList(firebase.database().ref("/leaderboard"));

@dizzyrobin You’re correct, DocumentReference in react-native-firebase doesn’t implement the isEqual method, which is a bit unfortunate.

@cmmartin It might be worth raising an issue with them directly to see if they can add it either to v5 or their upcoming v6.

In the meantime, I’ll have a think to see if this can be worked around in any way.
