Getting a.ref is not a function error when upgrade

问题:

Following codebase used to work with firebase 2.3.1 and Angularfire 1.1.3

Var fb = new firebase("https://database name.firebaseio.com");

var fbObj = $firebaseObject(fb.child("users/" + userId));

I upgraded to firebase3.0 and Angularfire 1.2.

As a result, here is how the above code got modified:

var config = {/* ...  */};
firebase.initializeApp(config);
var fb = firebase.database().ref();

var fbObj = $firebaseObject(fb.child("users/" + userId))

The above code however threw error such as a.ref is not a function when instantiating fbObj.

Please suggest.

you should not upgrade your firebase to 3.0 because AngularFire upgrade to 3.0 has not been completed.
