CollectionReference.doc() requires its first argument to be of type non-empty string

I have an ionic app trying to update the records in firebase. I keep on getting this error. Not sure what I am doing wrong.

Error: Uncaught (in promise): FirebaseError: [code=invalid-argument]: Function CollectionReference.doc() requires its first argument to be of type non-empty string, but it was: a custom Object object

FirebaseError: Function CollectionReference.doc() requires its first argument to be of type non-empty string, but it was: a custom Object object

this is my update function.

updateTodo(todo: Todo, id: string) {

    return this.todosCollection.doc(id).update(todo)
}

In my case I was passing a number type variable in the .doc function but it requires a string. Verify that your "id" variable has a value and it is not undefined, null or and empty string.

I had this problem and solved it by typing .doc(cred.user.uid) instead of .doc(cred.user.id).

Go where you're calling that function updateTodo use uid instead of id.

The problem is on the id that you are passing in doc,it is supposed to be a string..try logging its value just to check what you are exactly passing

This happens when you are trying to send an empty object to firebase. I had this error when I reset my form values before the async call could finish..
