PowerCLI 13.0.0 b20829139 - New-WMNamespacePermission completes permission creation but gives error

I've been working on a PowerCLI script to integrate with our catalog for adding a new VMware Workload Namespace and assigning the admin team permissions. The script is working and even the permissions are being added properly, but the error still triggers a failure result. Any ideas if this is a bug or something I'm missing? 

This is the command the script runs: 

New-WMNamespacePermission -Namespace $OUR-APP-NAMESPACE -Role Edit -Domain $INTERNALSSODOMAIN -PrincipalType User -PrincipalName $ADMINUSERNAMEHERE


New-WMNamespacePermission : 1/25/2023 10:40:19 AM       New-WMNamespacePermission               Sequence contains no matching element
At line:1 char:1
+ New-WMNamespacePermission -Namespace OUR-APP-NAMESPACE -Role Edit -Doma ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [New-WMNamespacePermission], VimException
    + FullyQualifiedErrorId : Core_BaseCmdlet_UnknownError,VMware.VimAutomation.WorkloadManagement.Commands.Cmdlets.NewWMNamespacePermission


The script completes with the error code returned but when checking in vCenter the permissions are defined and the users are able to authenticate properly.

Looks indeed like an issue.
You could try to provide a VIRole object (-Role (Get-VIRole -Name 'Edit'))instead of a String, but that is just a wild guess.
