When I was writing the webgis, I used eris’ API. The tutorial only taught how to use their own URL. When I used my own uploaded URL, it gave an error. How can I use my own URL?

const view = new MapView({
container: "viewDiv",

//Trailheads feature layer (points)
const trailheadsLayer = new FeatureLayer({
url: "https://services3.arcgis.com/GVgbJbqm8hXASVYi/arcgis/rest/services/Trailheads/FeatureServer/0"
});
map.add(trailheadsLayer);
//Trails feature layer (lines)
const trailsLayer = new FeatureLayer({
url: "https://services3.arcgis.com/GVgbJbqm8hXASVYi/arcgis/rest/services/Trails/FeatureServer/0"
});
map.add(trailsLayer, 0);
// Parks and open spaces (polygons)
const parksLayer = new FeatureLayer({
url: "https://services3.arcgis.com/qPQQycqtkiAa89x6/arcgis/rest/services/xishan/FeatureServer"
});
map.add(parksLayer, 0);
});

I tried to change the URL to my own, but it will throw an error saying it cannot find my URL in the FeatureLayer.
