Set-SwisObject error when updating IPAM.Subnet

I am executing the following command via powershell and getting an error.  However, despite the error it does update the FriendlyName in the database.  Any thoughts on how to get rid of the error?

Command:

Set-SwisObject -SwisConnection $swis -Uri 'swis://ORIONSERVER/Orion/IPAM.Subnet/SubnetId=14030,ParentId=7649' -Properties @{FriendlyName="TEST";}

Error:

Set-SwisObject : SolarWinds.IPAM.Contract.Service.IIpamGroupNodeProxy.Scan failed,

check fault information.
