I'm tryng to use the widget Utility Network Trace (BETA) in the Experience Builder Dev 1.9, and I saw this error.

Translate the error:
"This map does not support Utility Network tracing. Publish a web map with a shared utility network and Tracing Settings."
I followed the tasks in the Water Utility Network Foundation, to create de UN, and publish. I did the configuration about the tool Add Trace Configuration too, and was not a sufficient. How would I solve this problem to use a widget in the ExB.
