Error to using the Map Utility Network Editor Runtime

[MatheusSparapani]

ArcGIS Pro 2.9.4 and ArcGIS Enterprise 10.9.1

I followed the tasks in Water Utility Network Foundation, and, when I published the map "Utility Network Editor or Utility Network Editor Runtime",when I open the map in the Portal, I have errors to loading the features. 

When I open the feature service about Utility Network, the features loading correctly, but, when I open this map "editor", I have the errors.

In Map Viewer

Translate the error in image: There was an error loading this layer

In Map Viewer Classic

Translate the error in image: The Sewer Device layer is not a supported type and cannot be added to the map

The webmap created has subtype group layers in it, which are not supported in any of the web viewers yet.  Only runtime apps, like field maps.

As an update on this thread. Support for subtype group layers was added to the map viewer in ArcGIS Enterprise 11.1.
