I am attempting to query some FeatureLayers, but I cannot seem to construct a query that works. If you click on the map in the following demo the promise returns an error: ArcGIS: queryFeatures - Unsupported query error  message: "Unsupported query" name: "esri.layers.graphics.QueryEngine" I've tried a number of searches with different geometry types (extent, circle, geodesic buffer). I've also tried center and distance, but they are all unsupported. Question: how can I find out what kinds of queries FeatureLayers support? I have not come across docs that have helped in that regard. Besides my sample FeatureLayer there are other FeatureLayers I will be querying (e.g. remote ones) and I would like to figure out what I can and cannot send in a query. FYI, here is the code:     require([       "esri/Map",       "esri/views/MapView",       "esri/layers/FeatureLayer",       "esri/geometry/geometryEngine",       "esri/Graphic",       "esri/layers/GraphicsLayer",       "esri/tasks/support/Query",       "esri/widgets/CoordinateConversion",       "esri/geometry/support/webMercatorUtils",       "esri/geometry/Point",       "dojo/domReady!"     ], function(Map, MapView, FeatureLayer, geometryEngine, Graphic, GraphicsLayer, Query, CC, wMU, Point) {       map = new Map({         basemap: "topo-vector"       });             view = new MapView({         container: "viewDiv",         map: map,         center: [-118.739851, 34.090456],         zoom: 14       });             view.ui.add(new CC({ view: view }), 'bottom-right');             featureLayer = new FeatureLayer({         id: 'dots',         title: 'dots on a map',         geometryType: 'point',         objectIdField: 'id',         spatialReference: { wkid: 4326 },         source: [],         fields: [           {             name: 'id',             alias: 'ID',             type: 'oid',           },           {             name: 'mapObject',             alias: 'mapObject',             type: 'object'           }         ]       });             map.layers.add(featureLayer);             var circleGraphic;             points = [];             [         '-118.742555, 34.095076',         '-118.747447, 34.094010',         '-118.749593, 34.090811',         '-118.734658, 34.088039',         '-118.736032, 34.091735',         '-118.743070, 34.091096'       ].forEach(pair => {         var ll = pair.split(', ');         addPoint(new Point({           type: 'point',           spatialReference: { wkid: 4326 },           x: ll[0],           y: ll[1]         }));       });             view.on('click', function (e) {         var centerPt = e.mapPoint;         if (e.native.ctrlKey) {           // add more points to the map           addPoint(centerPt);         } else {           // search in the clicked area for points           var geom = geometryEngine.geodesicBuffer(centerPt, 400, 'meters');           if (circleGraphic) view.graphics.remove(circleGraphic);           circleGraphic = new Graphic({             geometry: geom,             symbol: {               type: 'simple-fill',               color: [140, 140, 222, 0.5]             }           });           view.graphics.add(circleGraphic);                     query = featureLayer.createQuery();           query.geometry = geom;           query.spatialRelationship = 'contains';                     featureLayer.queryFeatures(query)             .then(result => {               console.log('This area contains', inPts.length, 'points');             }).catch(error => {               console.error(error);             });         }       });             function addPoint(geo) {         if (geo.spatialReference.isGeographic) {           geo = wMU.geographicToWebMercator(geo);           console.log('converting geography');         }         var pt = new Graphic({           geometry: geo,           symbol: {             type: 'simple-marker',             style: 'circle',             color: 'black',             size: '8px'           }         });         // console.log('adding point at:', pt.geometry.x, pt.geometry.y);         view.graphics.add(pt);         points.push(pt);       }     });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...
