Получение этой ошибки в консоли при попытке получить данные из API. У кого-нибудь была эта проблема раньше?

var url = "https://api.website.com/get/?type=events&lat=" + localStorage.getItem('latitude')
+ "&lng=" + localStorage.getItem('longitude') + "&distance=50";

$http({
    headers: {
        'Content-type': 'application/json'
    }
})

$http.get(url).success(function (events) {
    $scope.events = events;
});

ошибка:

TypeError: Cannot read property 'protocol' of undefined
