Querying a feature layer with a large amount of points

Barty

Greetings! Working in ArcGIS JS API 4.22:

I am trying to query a feature layer (polygons) with a large amount of points (~1000) in order to find which polygons the points intersect with (by name only, no need for geometries. Doing this with a loop for each point individually is extremely slow and errors out. I've tried condensing the points to a multipoint geometry in hopes of speeding the process to no avail. Is there a solution to this that I am just overlooking?

const layer = new FeatureLayer({
            url: "https://arcgis-server.lsa.umich.edu/arcgis/rest/services/IFR/glahf_classification_poly/MapServer/0",
            outFields: ["AEU_Code"],
        });
//gets a server error at about 250 points
var multipoint = new Multipoint({
            points: [
                [-86, 45],
                [-85, 47],
                [-84, 49]
            ]
        });

        const query = new Query();
        query.geometry = multipoint;
        query.outSpatialReference = { wkid: 102100 };
        query.returnGeometry = false;
        query.outFields = ["AEU_Code"];

        layer.queryFeatures(query).then(function (results) {
            console.log(results.features);  // prints the array of features to the console
        });

Thanks!

See if you can do this querying on the client side rather than calling on the server.
