Rename Portgroup give error, "Unexpected error checking compliance: 'None Type' object has no attribute 'checkBeacon' "

Hello,

I am using a script in my environment which renames PortGroup

what I do is"$PortGroup | Set-VirtualPortGroup -Name $pgNameNew -VLanId $vlanID | out-null"

the command goes fine, when I check the profile it shows not compliant (as expected).

then I used same command and renamed the PortGroup back to orignal name and check compliance,

this time it gives error "Unexpected error checking compliance: 'None Type' object has no attribute 'checkBeacon' "

the same process done via GUI works fine.

Any Idea , what am I missing here?

All the hosts are on 5.1

regards,
