Why will one particular layer from my database not load into Pro?

Question

I have a project with multiple layers from my database loaded in to it.  However, I have one layer that won't load into the map.  It's just a simple line layer.  It gives me the error message::   "Failed to add data, unsupported data type."

Any ideas?

Thank you Dan.  I just searched and found this question.  Yes, I will post my question again in the Pro SDK.

ArcGIS Pro SDK‌ might be a better place to post your query... this thread is quite old

I have same error in Pro.  I was trying to add a layer from my file geodatabase using Pro SDK.  Keep getting "Failed to add data, unsupported data type".  I can manually add it to Pro without any issues.  Any ideas?

Here are my codes:

await QueuedTask.Run(()=> 
 { 
 Uri uri = new Uri(sPrjDB + "\Map\Map.gdb\Pipe");
 LayerFactory.Instance.CreateLayer(uri, MapView.Active.Map);
 });
