xExchangeHelper.psm1 - Export-PSSession not creating temporary directory Server 2019

[erjenkin]

Problem description

I found that something may have changed from an OS (Server2019) perspective that isn't allowing the following command to succeed:
Export-PSSession -Session $Session -OutputModule $script:DSCExchangeModulePath

When attempting to use the config on a newly deployed exchange server an error regarding -OutModule would be displayed

Verbose logs

See above

DSC configuration

xExchDatabaseAvailabilityGroup DAG
        {
            Name                           = 'DAG1'
            Credential                     = $DomainCreds
            AutoDagTotalNumberOfServers    = 4
            AutoDagDatabaseCopiesPerVolume = 2
            DatacenterActivationMode       = 'DagOnly'
            SkipDagValidation              = $true
            WitnessDirectory               = 'Z:\witness01\DAG01'
            WitnessServer                  = $witnessServer
            AutoDagAutoReseedEnabled       = $true
        }

Suggested solution

New-Item -Path $script:DSCExchangeModulePath -Type Directory -Force

This happens also on Windows 2016 with Exchange 2016.
