All -
Sorry if I am missing something simple here, but when I try to update a pipeline isolation subnetwork I get an error that process encountered an "invalid device" when I'm certain that device is present in the subnetwork definition.
Here are the details. First, here's the error message:

I then search for the offending features in the PipelineDevice class using the GlobalIDs listed in the error. Here's what I get (why there are 5 GlobalID values in the error and only one feature returned on the query is another question... but one step at a time.)

The offending feature's Asset Group is "Pressure Recording Device" and Asset Type is "Unknown". So I check the subnetwork definition and see this:


The Asset Group/Asset Type seems to be present in the Isolation tier subnetwork definition.
Any pointers on what I am missing would be greatly appreciated.
Thanks,
Ed
