to access error have define error handler in description of angular $resource api.

                    $scope.error = error; 
$scope.update = function (id) {                 topic.get({id: id}, function (result) {                     $scope.name = result;                     $('#savetopicmodal').modal('show');                     console.log(result);                 }, function (error) {                                             console.log(error);                     $scope.error = error;                 });             };
