Has anyone been able to publish a trace tool as a geoprocessing service to use as a GP widget in an app in Portal? I tried a connect trace, which has very few parameters, but when I ran it in the app I got a ton of errors, saying Implementation of this Tool's Validate is invalid. The server logs did not yield much more info.
I'm using ArcGIS Pro 2.6, logged in as the portal admin / utility network owner; Enterprise is 10.8.1.
