How to get user coordinates in yandex maps?

Question

JavaScript

There is a code:

ymaps.ready(init);

function init() {
    var myMap = new ymaps.Map(\"map\", {
            center: [".$this->coords."],
            zoom: ".$this->zoom."
        });
    var geolocation = ymaps.geolocation,
        coords = [geolocation.latitude, geolocation.longitude];
        
        //кнопка
    var myButton = new ymaps.control.Button('Проложить маршрут');
myButton.events
    .add('click', function () {
            ymaps.route([
        [".$this->coords."],
        coords,
    ]).then(function (route) {
        myMap.geoObjects.add(route);
        var points = route.getWayPoints(),
            lastPoint = points.getLength() - 1;
        points.options.set('preset', 'twirl#redStretchyIcon');
        points.get(0).properties.set('iconContent', 'Точка отправления');
        points.get(lastPoint).properties.set('iconContent', 'Точка прибытия');

    }, function (error) {
        alert('Возникла ошибка: ' + error.message);
    });
    });
myMap.controls.add(myButton);

}

gives an Internal Server Error when you click on the "lay route" button.
Everything works if you do not determine the position of the user, but insert any coordinates. Accordingly, I'm stupid here:

var geolocation = ymaps.geolocation,
        coords = [geolocation.latitude, geolocation.longitude];

What's wrong here? How to get the user's coordinates into the coords variable.

Вы хотя бы пример из документации смотрели? Найдите пять отличий. Функция не мгновенная, нужен callback.
