Delete Field in Firestore Document

Question

how to delete a Document Field in Cloud Firestore? ... I'm using the code below but I can not.

this.db.doc(`ProfileUser/${userId}/followersCount/FollowersCount`).update({ 
[currentUserId]: firebase.firestore.FieldValue.delete()})

Anyone know how to do it?

You can try as shown below:

// get the reference to the doc
let docRef=this.db.doc(`ProfileUser/${userId}/followersCount/FollowersCount`);

// remove the {currentUserId} field from the document
let removeCurrentUserId = docRef.update({
    [currentUserId]: firebase.firestore.FieldValue.delete()
});
