Angular.js Authentication with Node.js

I'm unable to login with front-end might be problem with Angular-ui-Router. When I click on login button first I got an error as 'Possibly unhandled rejection' then I injected '$qProvider' in config file after adding $qProvider I don't see any error in console but the page is not changing it state whereas in the network tab i can see the Token is sent from the server. Can some one please help me.

App.config.js

angular.module('myApp', ['ui.router', 'myAppModel'])
        .config(function($qProvider, $stateProvider, $urlRouterProvider) {
            $urlRouterProvider.otherwise('/');
            $qProvider.errorOnUnhandledRejections(false);
            $stateProvider
                .state('base', {
                    abstract: true,
                    views: {
                        'nav@': {
                            template: '<navigation1></navigation1>'
                        }
                    }
                })
                .state('base.login', {
                    parent: 'base',
                    url: '/',
                    views: {
                        'main@': {
                            template: '<login></login>'
                        }
                    }
                })
                .state('base.register', {
                    parent: 'base',
                    url: '/register',
                    views: {
                        'main@': {
                            template: '<register></register>'
                        }
                    }
                })
                .state('base.dashboard', {
                    parent: 'base',
                    url: '/dashboard',
                    views: {
                        'main@': {
                            template: '<dashboard></dashboard>'
                        }
                    }
                })
        });
