Trying to highlight features click on in Exp Builder map

Hi, I am trying to customize the Exp Building Map Widget with a on click event to highlight and select the features I click on at that spot for instance both the building and parcel at that point. The issue I am having is it will not highlight and I haven't been able to figure out why.

Here is my snippet of code in the widget.tsx file:

jmv.view.on("click", function(event) {

if(jmv) {

let myLayers: String = ""

if (identifyLayers.trim() == "") {

myLayers = bufferLayers;

} else {

myLayers = identifyLayers + "," + bufferLayers

}

const myClickableLayers = myLayers.split(',')

const mapLyrVws = jmv.jimuLayerViews

const dsObj = DataSourceManager.getInstance()

for (const key in mapLyrVws) {

const ds = mapLyrVws[key].id

const lyrVw = mapLyrVws[key]

if (myClickableLayers.includes(lyrVw.layer.title)) {

//if (lyrVw.layer.popupEnabled) {

let query = lyrVw.layer.createQuery();

query.geometry = jmv.view.toMap(event);

query.returnGeometry = true;

query.outFields = [ "*" ]

lyrVw.layer.queryFeatures(query).then(function(results) {

if (lyrVw.layer.title == "Buildings") { // || lyrVw.layer.title == "Parcel QL" || lyrVw.layer.title == "PARCEL No Buildings") {

alert(lyrVw.type)

alert(results.features[0].attributes.OBJECTID)

lyrVw.selectFeatureById(results.features[0].attributes.OBJECTID)

const myExtent = results.features[0].geometry.extent.expand(extent_level)

jmv.view.goTo(myExtent)

}

})

//}

}

});

I used the highlight method. Here is the link to the sample code from ESRI.

Did you use a Web Map or a Web Scene for the Map Source?

I used a Web Map.

I have tried that as well but so far it hasn't lit the feature. Are you doing in the Map Widget? Did you set it up in the widget.tsx?

I set it up in the widget.tsx. I used the hitTest() method to return the layers I clicked on.
