TypeError: Cannot read property 'Scroll' of undefined

[mikeruto]

Hello I have an error with the scroll: TypeError: Cannot read property 'Scroll' of undefined.
I have this firebase structure:

my controller:
app.factory('tablas3', function ($firebaseArray) {
var tablas3 = firebase.database().ref().child("tabla3");
var tabla3Partido = new firebase.util.Scroll(tablas3, 'description');
return $firebaseArray(tabla3Partido);
});

my app.js:
angular.module('crud', ['ionic', 'angularMoment', 'ngCordova', 'ngCordovaOauth', 'firebase','firebase.utils'])

my index.html:
<script src="lib/firebase/firebase.js" type="text/javascript"></script>
<script src="lib/firebase-util/dist/firebase-util.min.js" type="text/javascript"></script>
<script src="lib/firebase-util/dist/firebase-util-paginate.min.js" type="text/javascript"></script>
<script src="lib/angularfire/dist/angularfire.min.js" type="text/javascript"></script>
<script src="js/app.js"></script>

I followed this example: https://jsfiddle.net/katowulf/a67hfo6j/
My error is in my controller in this line: var tabla3Partido = new firebase.util.Scroll(tablas3, 'description');
My firebase version is: Firebase v3.7.0

Hi thank you for your answer,

I know it is old, but I have to get an old app back on track and I am stuck.
It seems, my problem is different : it is "firebase.util" which is undefined in my code.

Here is my code :

		var rootRef = firebase.database().ref();
		var authUsersRef = rootRef.child("authUsers");
		
		authUsersRef.once('value', function(data){
			console.log(data.val());
			// => returns the object properly
		});
		var scrollRef = new firebase.util.Scroll(rootRef, 'lastOnline');
		

I have tried, multiple things, but I don't find the right way to include "firebase-util" :

When I call it in app.js
angular.module('starter', [ 'ionic', 'ionic.rating', 'tabSlideBox', 'firebase', 'firebase-util', ...
with in my index.html : <script src="https://cdn.firebase.com/libs/firebase-util/0.2.5/firebase-util.min.js"></script>
=> Failed to instantiate module firebase-util due to: [$injector:nomod] Module 'firebase-util' is not available!

When I don't: angular.module('starter', [ 'ionic', 'ionic.rating', 'tabSlideBox', 'firebase', ...
=> firebase.util is undefined

I see that you wrote : 'firebase.utils' in your angular.module => is there anything I am missing ?

Sorry I am not an expert,

Thank you in advance,

David

Mmm, this is a pretty old library which is not being developed anymore but it seems a problem with the library setup. See #3 and #4.
