Thanks for reporting this @scsibug. I could reproduce the issue at my side and would be investigating this ahead with the team. I would share updates soon.

How is this a feature request? The feature is clearly documented in the help page (az eventhubs namespace list), where it lists the option --subscription : Name or ID of subscription. Simply using that argument in a brand new cloudshell today continues to give the stacktrace from the original report.

Documented features giving stacktraces seems like a bug, no?
