Using KML layer in ArcGIS API for JS 4.7 ?

[rishishady]

I have KML layer and I couldn't use it in KMLLayer module from JavaScript API. Is there any limitation or something else.?

From the documentation:

Known Limitations

• Currently, the KMLLayer is not supported in SceneView.
• MapImage is only supported when the MapView's spatial reference is WGS84 (wkid: 4326).
• More information can be found here about limitations using KML layers.

Also,

The KMLLayer uses a utility service from ArcGIS.com, therefore your kml/kmz files must be publicly accessible on the internet. If the kml/kmz files are behind a firewall you must to set the esriConfig.kmlServiceUrl to your own utility service (requires ArcGIS Enterprise).
