I have the trace network published already, and I can bring it into Pro and use it successfully. My problem is that all attempts to bring it into a web map fail.
The Map Viewer in Portal shows an error indicator for the Trace Network layer when I add the service to it.
I tried your suggestion in another post of adding the published feature service to Pro and publishing the web map from there, but Publishing fails.
All of this might be a moot point anyway if the existing widgets don't work with a Trace Network. If I have to build my own web app to run traces, then I can hit the rest endpoint directly.
I was just hoping for something plug-and-play.
