Failing to query attributes of custom LayerView

I'm generating and adding graphics to a client-side feature layer, but, after the LayerView updates, I cannot query on all of its attributes--only on its OBJECTID. Why am I not getting any other attributes?

To the "Create a FeatureLayer with client-side graphics" example, I have added the following snippet in addToView(). (See Codepen.)

view.whenLayerView(layer).then(lyrView => {

lyrView.watch("updating", updating => {

if (!updating) {

console.error("Assert > 1 availableFields", lyrView.availableFields.length > 1);

lyrView.queryFeatures({outFields: ["OBJECTID","url"]}).then((graphics)=>{

console.error("Assert _any_ graphics have an 'OBJECTID' attribute", graphics.features.filter(f => {return f.attributes["OBJECTID"]}).length > 0);

console.error("Assert _any_ graphics have a 'url' attribute", graphics.features.filter(f => {return f.attributes["url"]}).length > 0);

})

}

});

The console output I receive follows:

Assert > 1 availableFields false

_Any_ graphics have an 'OBJECTID' attribute true

_Any_ graphics have a 'url' attribute false

I expected to see availableFields having a length of 2 and to find "url" attributes in the query results.

You'll need to add the outFields parameter to your layer's constructor:

outFields: ["OBJECTID","url"],

This is somewhat implied by the documentation for the availableFields property.
