Utility Network Change Asset Package Spatial Reference gives error "The domain was not found"

Question

I am using ArcGIS Pro 3.0.2 and going through the "Use Sewer Utility Network Foundation" to better understand the Utility Network in preparation for migrating from a geometric network to the Utility Network.  I followed all the steps up to "Project and Remove Sample Data".  When I run that task using the supplied Asset Package as input  (Sewer_AssetPackage.gdb) and naming a new Package as output, I get the message "The domain was not found" for each domain in the input database.  Was I supposed to load all the domains to the output database before running the task?  Thanks for any info you can provide.

There is an issue when applying the asset package in a pro project with maps in it, even if they are closed an never opened.  Try applying the asset package with with a pro project with no maps in it.
