Looking for the nearest object on the map?

Question

API

I have a collection of my points (elements) on a map. There are 20 of them now. I need to determine the user's location by clicking and search for the nearest point that is on the map.

GeoQueryResult(objectCollection.toArray()).getClosestTo(result.geoObjects.get(0).geometry._coordinates).balloon.open();

objectCollection- a collection of points on the map - user coordinates (everything works well here) If you try the example from Yandex , then everything is fine, BUT if I replace the cafe variable from the example with my collection, then nothing works. Maybe I need to convert my collection to something else? Collection does not work.
result.geoObjects.get(0).geometry._coordinates

Answer 1

Issue resolved.

ymaps.geoQuery(myMap.geoObjects).getClosestTo(result.geoObjects.get(0).geometry._coordinates).balloon.open();
