AngularJS ui-router otherwise to state instead of url?

Question

I am using AngularJS and ui-router and in my app.js. I have the following line:

$urlRouterProvider.otherwise(\'/\');

However

Answer 1

Try This.

$urlRouterProvider.otherwise(function($injector, $location){
    $injector.get('$state').go('404');
});

Answer 2

I think you achieved that with this code

$urlRouterProvider.otherwise(function($injector, $location){
  $injector.invoke(['$state', function($state) {
    $state.go('404');
  }]);
}); 

Answer 3

Just a small improvement to @kdlcruz's answer:

$urlRouterProvider.otherwise(function($injector){
    $injector.invoke(['$state', function($state) {
        $state.go('404', {}, { location: false } );
    }]);
});

By doing that, you still able to keep the incorrect the URL and only state is changed.
