What did you expect: An error message indicating that "id" is not a valid column. Ideally, would list the acceptable/valid values.

Anything else you would like to add:

Environment:

• kapp version (use kapp --version): 0.54.3
• OS (e.g. from /etc/os-release): (all)
• Kubernetes version (use kubectl version): n/a

This would require making some changes in the underlying ui library.
