New-CMTaskSequenceMedia Help : Object Reference Not Set to Instance of Object

Question

Having trouble creating a script to automate creation of bootable task sequence media. The following returns "Object Reference not set to an instance of an object" and I can't seem to figure it out:
Import-Module (Join-Path $(Split-Path $env:SMS_ADMIN_UI_PATH) ConfigurationManager.psd1)
cd CM1:
$hash =@{}
$MPServers = @("Server003.fqdn.com","Server004.fqdn.com","Server005.fqdn.com")
$StartDate = (Get-Date -Format "MM/dd/yyyy.HH:mm:ss").ToString()
$EndDate = "08/07/2025.12:12:12"
<#This section to be finished later:
#$hash.Add("SMSTSPreferredAdvertID","CM10017A")
#$hash.Add("OSDComputerName","BLDTMP08R2")
#$hash.Add("SMSTSPreferredAdvertID","CM100169")
#$hash.Add("OSDComputerName","BLDTMP2012")

$hash.Add("SMSTSPreferredAdvertID","CM10016A")

We are running R2 CU2.
When I ran the command with -Verbose I recieved:

Since it seemed to fail while pulling the MPs I switched to using just one MP as you had above, this time I get a different error:
