firestore Error: Argument "documentPath" must point to a document

Question

I build react native app with firebase/firestore and I get the error

Error: Argument "documentPath" must point to a document.

when I write this line

    var userStatusFirestoreRef = firebase.firestore().doc('/status/' + uid);

all code

    firebase.auth().signInAnonymouslyAndRetrieveData().then((user) => {
    var uid = firebase.auth().currentUser.uid;

    var userStatusFirestoreRef = firebase.firestore().doc('/status/' + uid);
});

Answer 1

You should chain the collection() and doc() methods for each segment of the firestore path, example:

firebase.firestore().collection('status').doc(uid)

You can chain these as far as your subcollections and subdocuments go.

firebase.firestore().collection('status').doc(uid).collection('messages').doc('messageId')

Answer 2

UPDATE : now you can't put a forward slash '/' in a document's name, it throws the error:

firebase.firestore().collection().doc(*) 'document path' must point a docment

Answer 3

I found the error, it should be

    var userStatusFirestoreRef = firebase.firestore().doc('status/' + uid);

with one '/' at the end of 'status/'
