AngularJS possible unhandled rejection when using

Question

After I have changed from ngRoute to angular-ui-router the console shows always 4 errors stating: Possibly unhandled rejection: {}

I did not noticed any "problem" in the behavior of the application I am building, but I would like to get rid of it.

Any idea what does it mean and how to solve it?

Here an screenshot:

Answer 1

This issue is found in 1.5.9 and 1.6.0-rc-0. More details at https://github.com/angular-ui/ui-router/issues/2889

Patch solution is to manually disable unhandled rejections.

app.config(['$qProvider', function ($qProvider) {
    $qProvider.errorOnUnhandledRejections(false);
}]);

Answer 2

I used the next solution

    $http.get('/api/get').then(function(result) {
       // ... stuff here
    }).catch(angular.noop);

it's equals to

$http.get('/api/get').then(function(result) {
  // ... stuff here
}).catch(function(){});

Resolve the promise with false if you are trying to abort a transition.
