Get-GPOReport Remote PowerShell Session

Hello,

I have a custom PowerShell configuration (PSSessionConfiguration w/ Startup Script) to allow some folks the ability to run a subset of cmdlets from a remote session. This has been working great and I wanted to extend the functionality to incorporate the Get-GPOReport cmdlet. So as I have in the past, I added this cmdlet to my $allowedCmdlets array in the startup script for this session configuration. When I enter a remote session under this configuration and execute the cmdlet with the -ReportType parameter as "Xml" (Get-GPOReport -ReportType Xml) I get the following error:

Operation is not valid due to the current state of the object.
    + CategoryInfo          :
    + FullyQualifiedErrorId : System.InvalidOperationException,Microsoft.GroupPolicy.Commands.GetGpoReportCommand

I can run the same cmdlet with the -ReportType parameter as "Html" (Get-GPOReport -ReportType Html) and it works like a champ. I have a feeling the start up script for the session configuration is limiting too much and preventing the XML output from the Get-GPOReport cmdlet to be displayed. Not sure though.

Can anyone help me work through this, please?

PSSessionConfiguration Startup Script:

##--LOAD SESSION MODULES--##
Import-Module ActiveDirectory
Import-Module GroupPolicy
##--RESTRICT ACCESS TO ALL CMDLETS, VARIABLES, APPS FIRST--##
Foreach ($command in Get-Command) {$command.Visibility = "private"}
Foreach ($variable in Get-Variable) {$variable.Visibility = "private"}
$ExecutionContext.SessionState.Applications.Clear()
$ExecutionContext.SessionState.Scripts.Clear()
$ExecutionContext.SessionState.LanguageMode = "NoLanguage"
$InitialSessionState = [Management.Automation.Runspaces.InitialSessionState]::CreateRestricted("RemoteServer")
Foreach ($proxy in ($InitialSessionState.Commands | Where {$_.Visibility -eq "Public"})) {
	$cmdlet = Get-Command -CommandType cmdlet -ErrorAction SilentlyContinue $proxy.Name
	If ($cmdlet) {
		$alias = Set-Alias "$($proxy.Name)" "$($cmdlet.ModuleName)\$($cmdlet.Name)" -PassThru
		$alias.Visibility = "Private"
	}
	Set-Item "function:global:$($proxy.Name)" $proxy.Definition
}
##--GRANT ACCESS TO SPECIFIC CMDLETS--## 
$allowedCmdlets = @("Get-ADUser", "Get-ADGroup", "Get-ADGroupMember", "Get-GPO", "Get-GPOReport")
