Angular.js $ http.post TypeError: no se puede leer la propiedad ''datos'' de indefinido

Question

Angular.js v1.0.6

Al hacer un $ http.post y recibir un resposne no 200 (401 en este caso)

$http.post(''http://localhost:3030/auth/login'', {
  username: ''username'',
  password: ''password''
})
.success(function(data) {
  // Gets called on a 200 response, but not on a 401
  console.log(''success'');
})
.error(function(err) {
  // Never gets called & dies with error described below.
  console.log(''error'');
});

Angular arroja el siguiente error:

TypeError: Cannot read property ''data'' of undefined

    at wrappedCallback (http://localhost:9000/components/angular/angular.js:6797:59)

    at XMLHttpRequest.xhr.onreadystatechange (http://localhost:9000/components/angular/angular.js:9244:11) 

Y nunca llama a la devolución de llamada .success() ni a la .error() lo que imposibilita el manejo de la respuesta.

¿Estoy haciendo algo mal? La devolución de llamada exitosa se realiza como se espera al proporcionar las credenciales legítimas.

  "auth-token":"676932cc1e183a64334345944ad432d1908f8110bc",
  "user": {
    "id":1,
    "username":"username"
  }
}

401 respuesta:

Access-Control-Allow-Headers:Content-Type, Authorization, Content-Length, X-Requested-With, Auth-Token
Access-Control-Allow-Methods:GET,PUT,POST,DELETE,OPTIONS
Access-Control-Allow-Origin:*
Connection:keep-alive
Content-Length:45
Content-Type:application/json

{
  "error": [
    {
      "message":"Invalid Credentials"
    }
  ]
}

Además, si adopto la sintaxis de promesa normal a favor de los accesos directos de .success () obtengo un comportamiento interesante:

$http.post(''http://localhost:3030/auth/login'', {
  username: username,
  password: password
}).then(function (resp) {
  // On a 200 response, resp is a response object.
  // On a 401 response, resp is undefined.
  console.log(resp);
}, function() {
  console.log(''error'');
});

Finalmente llegamos al fondo de esto. El problema se debió a la siguiente implementación de interceptor HTTP global:

''use strict'';
// register the interceptor as a service
angular.module(''imvgm'')
  .factory(''httpInterceptor'', [''$q'', ''$rootScope'',  function($q, $rootScope) {

  function success(response) {
    return response;
  }

  function error(response) {
    var status = response.status;

    if (status === 401) {
      $rootScope.$broadcast(''event:loginRequired'');
      return
    }
    // otherwise
    return $q.reject(response);
  }

  return function(promise) {
    return promise.then(success, error);
  };

}]);

nótese bien

if (status === 401) {
  $rootScope.$broadcast(''event:loginRequired'');
  return // Returns nothing
}

FIJAR:

if (status === 401) {
  $rootScope.$broadcast(''event:loginRequired'');
}
