angularjs - 401 error code interpreted incorrectly in angular -

i relatively new angular not sure if missing here.

i have http interceptor adding jwt tokens requests handling responses server.

.factory('myhttpinterceptor', ['$q', '$location', '$window', function($q, $location, $window) {    return {        request: function(request) {            console.log('myhttpinterceptor - request');            return request;        },        requesterror: function(requesterror) {            console.log('myhttpinterceptor - requesterror');            return requesterror;        },        response: function(response) {            console.log('myhttpinterceptor - response');            return response;        },        responseerror: function(responseerror) {            console.log('myhttpinterceptor - responseerror');            return responseerror;        }    }; }]);   //http intercpetor check auth failures  angular.module("posmobile").config(['$httpprovider', function($httpprovider) {    $httpprovider.interceptors.push('myhttpinterceptor'); }]); 

so here problem, trying handle 401 unauthorized error changing route login screen responseerror listener doesn't ever seem fire.

i have checked iis logs , service returning 401 code

here did test using postman , picked 401screenshot of postman

however in interceptor evaluates xdk debug screenshot

and after request completed 401 error in debug console

thanks in advance
