Not Able To See Buffer on Click Event On Graphics Layer

Question

Using ArcGIS JavaScript API 3.21 and This Demo Fiddle I am trying to create a buffed area on click event but apparently this is not showing any graphic on bufferLayer graphics Layer require([ "esri/map", "esri/SpatialReference", "esri/graphic", "esri/layers/GraphicsLayer", "esri/Color", "esri/geometry/Point", "esri/geometry/geometryEngine", "esri/symbols/SimpleMarkerSymbol", "esri/symbols/SimpleLineSymbol", "esri/symbols/SimpleFillSymbol", "esri/renderers/SimpleRenderer", "dojo/domReady!" ], function( Map, SpatialReference, Graphic, GraphicsLayer, Color, Point, geometryEngine, SimpleMarkerSymbol, SimpleLineSymbol, SimpleFillSymbol, SimpleRenderer ) { var map = new Map("map", { basemap: "streets", center: [-122.4, 37.785], zoom: 14, }); var buffSymb = new SimpleFillSymbol( SimpleFillSymbol.STYLE_NULL, new SimpleLineSymbol( SimpleLineSymbol.STYLE_SHORTDASHDOTDOT, new Color([105, 105, 105]), 2 ), new Color([255, 255, 0, 0.25]) ); var graphicsLayer = new GraphicsLayer(); var bufferLayer = new GraphicsLayer(); map.addLayer(graphicsLayer); map.on("click", function(evt){ var buffer = geometryEngine.geodesicBuffer( new Point(evt.mapPoint.x, evt.mapPoint.y), 1000, "meters" ); bufferLayer.add(new Graphic(buffer, buffSymb)); map.addLayer(bufferLayer); }); });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I am not getting any error message but also no result back! can you please take a look at this and let me know what I am doing wrong?

You can also use the mapPoint instance directly returned from the click event: var buffer = geometryEngine.geodesicBuffer(evt.mapPoint, 1000, "meters");

Hi @Bengi Geoca,

I was able to get a result with your example by adding spatialReference to the point past to the geometry engine.

Here is your demo modified: ArcGIS Add Point - JSFiddle.
