-PrincipalType and -Identifier parameters not recognised

I have a powershell script that uses PowerBI PS cmdlets to add user to a workspace, and it has stopped working since yesterday. I am using the Add-PowerBIWorkspaceUser function.

My original cCmdlet call is as follows;
Add-PowerBIWorkspaceUser -Id $workspace.Id -Identifier $wUser -AccessRight $pUserRole -PrincipalType $pPrincipalType where

• $workspace.Id = ID of the workspace
• $wUser = user email address
• $pUserRole = Member or Contributor
• $pPrincipalType = User

This has started to fail since yesterday (I haven't used them in a long time). Initially it started to fail saying that identifier is not a valid parameter entry

• Add-PowerBIWorkspaceUser : A parameter cannot be found that matches parameter name 'identifier'.

I replaced identifier with UserPrincipalName and now it has started fail saying that PrincipalType is not a valid entry.

• Add-PowerBIWorkspaceUser : A parameter cannot be found that matches parameter name 'PrincipalType'.

What am I doing wrong? I have updated the PBI PowerShell modules and my versions are below;

Thanks

Start with the Add-PowerBIWorkspaceUser cmdlet and inspect its currently supported parameters against the reported call using -Identifier, -UserPrincipalName, and -PrincipalType. Reproduce the parameter errors with the module versions shown in the issue, then verify the documented invocation and parameter behavior. Done means the cause of the rejected parameters is identified and the issue records the supported command usage.
