Not Able To Display Query Task Result on Graphic Layer

[BehrouzHosseini]

Using ArcGIS API 3.21 and following code I am trying to populate the result of a Query Task on map by populating the result featureSet on GraphicLayer but I am not getting any thing in result. and No error on Console. Can you please let me know what I am doing wrong?

var map;
 require([
 "esri/map", 
 "esri/layers/FeatureLayer", 
 "esri/layers/GraphicsLayer",
 "esri/tasks/query",
 'esri/tasks/QueryTask',
 'dojo/_base/array',
 "esri/graphic", 
 "esri/symbols/SimpleMarkerSymbol",
 "esri/Color", 
 "dojo/dom", 
 "dojo/domReady!"
 ], function(
 Map, FeatureLayer, GraphicsLayer, Query, QueryTask, array, Graphic, SimpleMarkerSymbol, Color, dom
 ) {
map = new Map("mapDiv", { 
 basemap: "streets",
 center: [-88.155000, 41.784042],
 zoom: 14,
 slider: false
 });
 
 var graphicsLayer = new GraphicsLayer();
 
 var markerSymbol = new SimpleMarkerSymbol(
 SimpleMarkerSymbol.STYLE_SQUARE, 10, null, new Color([50,50,255])
 );
 
  var queryTask = new QueryTask("https://server.domain.com/arcgis/rest/services/ElectricData/FeatureServer/3");
   
  var query = new Query();
   query.where = "1=1";
   query.returnGeometry = true;
   query.outFields = [ "CreationUser"];
   queryTask.execute(query).then(onQuerySuccess, onError);

  function onQuerySuccess(featureSet) {
    array.forEach(featureSet.features, function(feature) {
    feature.setSymbol(markerSymbol);
    graphicsLayer.add(feature);
   });
   map.addLayer(graphicsLayer);
  }

  function onError(error) {
    console.error('An error ocurred in the query: ', error);
 }
 
 });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Bengi,

   You need to set the queries outSpatialReference to the maps:

query.outSpatialReference = map.spatialReference;‍

[BehrouzHosseini]

Thanks for comment Robert I updated the code as:

query.where = "1=1";
 query.returnGeometry = true;
 query.outSpatialReference = map.spatialReference;
 query.outFields = [
 "CreationUser"
 ];‍‍‍‍‍‍

but still noting on the map!

[RobertScheitlin__GISP]

Bengi,

   Are getting to the onQuerySuccess function? Can you add a console statement to that function to test?

The way I normally have my querytask execute is this:

queryTask.execute(query, onQuerySuccess, onError);

[BehrouzHosseini]

I also tried to console.log() the results

 console.log(featureSet.features[i])‍‍

which I am getting this points

{type: "point", x: 1034892.977614373, y: 1871653.8816519529, spatialReference{wkid: 102671, latestWkid: 3435}}

[RobertScheitlin__GISP]

Bengi,

   What is returning from the query is still not the correct spatial reference then it is 102671 when it needs to be 102100. Can you show your latest updated code?

[BehrouzHosseini]

Sure here you are

var map;
 require([
 "esri/map", 
 "esri/layers/FeatureLayer", 
 "esri/layers/GraphicsLayer",
 "esri/tasks/query",
 'esri/tasks/QueryTask',
 'dojo/_base/array',
 "esri/graphic", 
 "esri/symbols/SimpleMarkerSymbol",
 "esri/symbols/SimpleLineSymbol", 
 "esri/symbols/SimpleFillSymbol", 
 "esri/renderers/SimpleRenderer",
 "esri/Color", 
 "dojo/dom", 
 "dojo/domReady!"
 ], function(
 Map, FeatureLayer, GraphicsLayer, Query, QueryTask, array, Graphic, SimpleMarkerSymbol, SimpleLineSymbol, SimpleFillSymbol, SimpleRenderer, Color, dom
 ) {
map = new Map("mapDiv", { 
 basemap: "streets",
 center: [-88.155000, 41.784042],
 zoom: 14,
 slider: false
 });
 var graphicsLayer = new GraphicsLayer();
 var markerSymbol = new SimpleMarkerSymbol(
 SimpleMarkerSymbol.STYLE_SQUARE, 10, null, new Color([50,50,255])
 );
 
 
 var queryTask = new QueryTask("https://server.domain.com/arcgis/rest/services/ElectricData/FeatureServer/3");
var query = new Query();
 
 
 query.where = "1=1";
 query.returnGeometry = true;
 query.outSpatialReference = map.spatialReference;
 query.outFields = [
 "CreationUser"
 ];
 queryTask.execute(query).then(onQuerySuccess, onError);
function onQuerySuccess(featureSet) {
array.forEach(featureSet.features, function(feature) {
feature.setSymbol(markerSymbol);
 graphicsLayer.add(feature);
});
 console.log(featureSet.features)
 map.addLayer(graphicsLayer);
 
}
function onError(error) {
console.error('An error ocurred in the query: ', error);
}
 
 
 });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

[RobertScheitlin__GISP]

Bengi,

Try changing this line for testing:

query.outFields = ["*"];

[BehrouzHosseini]

You are right it is actually adding the points to graphiclayer but somewhere in Africa!. Is there any way to update the spatialRefrence?

[BehrouzHosseini]

and when I try to get map spatial Reference

console.log(map.spatialReference);‍

it outputs undefine
