ArcGIS returns "IconSymbol3DLayer failed to load" when configuring a PictureMarkerSymbol

Question

I'm trying to add a PictureMarkerSymbol to a SceneView, but I'm getting the following error upon reloading the page:

[esri.views.3d.layers.graphics.Graphics3DSymbolLayer] IconSymbol3DLayer failed to load (Request for icon resource failed:

Here is how I'm configuring the PictureMarkerSymbol:

var source = {
    geometry: {
        type: "point",
        longitude: 86.845,
        latitude: 27.991,
        z: 5194.164
    },
    symbol: {
        type: "picture-marker",
        url: "http://icons.iconarchive.com/icons/designbolts/free-multimedia/1024/Photo-icon.png",
        width: 20,
        height: 20
    }
};

var flayer = new FeatureLayer({
    source: [source],
    fields: [],
    objectIdField: "ObjectID",
    geometryType: "point"
});
map.add(flayer);

Can you please help me understand what am I doing wrong?

Answer 1

You need to make sure a few things are covered:

1. You are saying your objectIdField is ObjectID but that does not appear in your (empty) fields array. You must have an entry in the fields array for this field that you're saying exists.
2. Instead of defining a symbol on feature, instead set a renderer on the FeatureLayer.
