IdentifyTask in API 4.6 trouble finding feature geometry

LoriEmerson_McCormack — Wed, 10 Jan 2018 22:58:15 GMT

I want to access the feature geometry when using the IdentifyTask in the JavaScript API 4.6 so that I can add a graphic to my point feature.

I am using the Sample located at https://developers.arcgis.com/javascript/latest/sample-code/tasks-identify/

I added a line

var mp = result.feature.geometry;

but the geometry is null.

Here is part of the code:

// Executes each time the view is clicked

function executeIdentifyTask(event) {

// Set the geometry to the location of the view click

alert (event.mapPoint.x);

params.geometry = event.mapPoint;

params.mapExtent = view.extent;

dom.byId("viewDiv").style.cursor = "wait";

// This function returns a promise that resolves to an array of features

// A custom popupTemplate is set for each feature based on the layer it

// originates from

identifyTask.execute(params).then(function(response) {

var results = response.results;

return arrayUtils.map(results, function(result) {

var feature = result.feature;

var layerName = result.layerName;

var mp = result.feature.geometry;

End of the code

Here is what the result object looks like in 4.6. How do I find the geometry? The "_proto_" and "_accessor_" make it difficult to find anything.

Lori,

I do not see in your code where you specify the returnGeometry property of the IdentifyParameters.

Lori,

Your issue is mis-punctuation of the property name the g has to be upper case

params.returnGeometry = true;

Silly me. Thanks, Robert.
