AngularJS SyntaxError: Unexpected token {

I have a code that works but when I check my console I'm getting SyntaxError: Unexpected token { and here is the screenshot:

And when I check line 58 of my studentController.js here it is console.log(error);. The complete code is:

angular
    .module('studentInfoApp')
    .factory('Student', Student)
    .controller('StudentsController', StudentsController)
    .config(config);

function config($routeProvider) {
    $routeProvider
    .when('/', {
        controller: 'StudentsController',
        templateUrl: 'app/views/student-list.html'
    })
}

function Student($resource) {
    return $resource('/students/:id');
}

function StudentsController(Student, $scope, $http) {

    $scope.inputForm = {};
    $scope.students = null;

    function initStudents() {
        Student.query(function(data, headers) {
            $scope.students = data;
            $scope.studentsPanel = true;
            console.log(data);
        }, function (error) {
            console.log(error);
        });
    }

    initStudents();

    $scope.addStudentForm = function() {
        $scope.loading = true;
    }

    $scope.cancelAddStudent = function() {
        $scope.loading = false;
    }

    $scope.addStudent = function() {
        $scope.studentsPanel = false;
        var data = {
            fname: $scope.inputForm.fname,
            lname: $scope.inputForm.lname,
            age: $scope.inputForm.age,
            email: $scope.inputForm.email
        }

        Student.save(data)
        .$promise.then(function successCallback(response) {
            initStudents();
            console.log(response); //line 58
          }, function errorCallback(error) {
            console.log(error);
          });
    }
}

Am I missing something here? Thank you.

UPDATE:

Managed to fix it by correcting some variable. In my php file:

$request = Slim\Slim::getInstance()->request();
$data = json_decode($request->getBody());
echo json_encode($data); 

It should be

echo json_encode($request);
