"Unknown Provider" in AngularJS

Question

I'm trying to load a few services and controllers into an AngularJS app but I am facing an "Unknown Provider" message that I don't understand.

Unknown provider: $scope, accountManagementServiceProvider <- $scope,
accountManagementService <- RegistrationSigninControllerS/<@https:
//ajax.googleapis.com/ajax/libs/angularjs/1.3.13/an… id

My app.js is like this

var dataApp = angular.module('niwadataApp', ['ngRoute','niwaDataControllers']);

along with some config stuff and routes etc etc. Then in a separate file I define some settings and attempt to load the services/controller

dataApp.value('isEmbedded', false); //And the other 'auth' settings

dataApp.service('authenticationService', ['$http', '$q', '$rootScope', '$location', 'authTimeout', 'authTimeoutUrl', 'authUrl',AuthenticationServiceImpl]);
dataApp.factory('authenticatingProxyService', ['authenticationService', 'isEmbedded', '$http', '$q', '$window', '$rootScope', AuthenticatingProxyServiceImpl]);
dataApp.service('accountManagementService', ['$q', 'authenticatingProxyService', AccountManagementServiceImpl]);
dataApp.controller('RegistrationSigninController', ['$scope, accountManagementService', RegistrationControllerImpl]);

The classes are all defined in their own files that are loaded before app.js, e.g.

var AccountManagementServiceImpl = function($q, auth) {

According to the error message it is looking for accountManagementServiceProvider but I've got a class called accountManagementServiceImpl and that is what I've specified in the dataApp.service( call. Have I missed something in the documentation that defines class names must end with 'Provider'? Which provider does it not know about? As far as I can see each controller, service and factory defines its requirements and should be able to be created.

You are missing some quotes.

Change this:

dataApp.controller('RegistrationSigninController', ['$scope, accountManagementService', RegistrationControllerImpl]);

to this:

dataApp.controller('RegistrationSigninController', ['$scope', 'accountManagementService', RegistrationControllerImpl]);
