How to get attributes of Web Map feature which user clicked on in custom widget in ArcGIS Experience Builder application?

Question

I have an ArcGIS Experience Builder application, which uses a Web Map I host in ArcGIS online. This Web Map contains a feature layer with several attributes, and I can use these in Experience Builder with the stock widgets (i.e. updating dynamic text based on attributes when the user clicks on a certain feature). I am now trying to write a custom widget using Jimu which displays some text when the user clicks on a feature:

 jmv.view.on('click', evt => {
 const point: Point = jmv.view.toMap({
 x: evt.x,
 y: evt.y
 })
 jmv.view.hitTest(evt).then((response) => {
 console.log(response.results[0].graphic.attributes)
 // Do things with the attributes of the clicked feature
 })
 })

However, this code only returns the ObjectID attribute of the clicked feature, and none of the others. How do I access the rest of the features?

Answer 1

The outFields property on the feature layer needs to be set to provide the desired fields before accessing the hitTest results.

Using a wildcard to enable all fields:

var layer = jmv.view.map.layers.getItemAt(0)
layer.outFields = ["*"]
// hitTest code below
