Prune Branch History Not Working

[LRoberts_RDM]

We are using a Trace Network which requires us to use branch versioning. One of our layers is updated each night with new information so the layer is growing very quickly, and we are beginning to see performance issues. We found that in the latest ArcGIS Pro release there is a new tool called Prune Branch History. When we run it, we get the following error. I cannot find any useful information online as to why this would be. We are using a branch version connection to the feature data set, we are disconnecting all users from the database before running.

Here are a few more shots of our environment.

GDB version

ArcGIS Pro version

Trace Network version

I'm trying to use this tool on a Utility Network layer that is versioned and branched, but I keep getting an error saying it's not versioned or branched. I'm using a direct SDE connection to the SQL Server database as the UN owner (or db admin - result is the same). What else should I do ?

Did you try using your editing service for the UN instead of a direct connect to the database? I believe the tool wants the service.
