I'm having a difficult time understanding what this DIS Validation error means, it shows up as "Critical" and when trying to publish the DIS Output shows a stack trace (below).

I've gone trough all my QAction files and neither them or protocol.xml shows any errors.

Restarting VS2022 does not help.

DIS Output:
