Closest Facility with Feature Layer from ArcGIS Online

albanajpaul

I am trying to use a feature layer from ArcGIS Online to be an input facility in my closest facility parameter. I just recently started using ArcGIS JavaScript API and I saw someone's example in this forum which looks similar to this:

            facilitiesFeatureLayer = new FeatureLayer(

                "https://services6.arcgis.com/dUO3N3UOHvGU89bM/arcgis/rest/services/Murals_20201103/FeatureServer/0", {

                    mode:FeatureLayer.MODE_SNAPSHOT

                });

            let featuresetFacilities = new FeatureSet({

            });

            featuresetFacilities.features = facilitiesFeatureLayer.graphics;

 

            function findClosestFacility(startFeature, facilityFeatures) {

                const closestFacilityTask = new ClosestFacilityTask({

                    url: "https://route-api.arcgis.com/arcgis/rest/services/World/ClosestFacility/NAServer/ClosestFacility_World/solveClosestFacility/",

                });

                const params = new ClosestFacilityParameters({

                    incidents: new FeatureSet({

                        features: [startFeature],

                    }),

                    returnRoutes: true,

                    returnFacilities: true,

                    defaultTargetFacilityCount: 3,

                });

                params.facilities = featuresetFacilities;

 

The code runs but returns no results:

In your codepen you are mixing 3.x and 4.x code; that won't work.  Here's a slightly modified version of your code that gets and sets the facilities before you start trying to call the solver:
