Error enabling CPU hotadd and Mem hotplug

I am trying to enable CPU and Mem hotplug on a newly deployed VM and I am getting the following error. It's powered off

PS C:\WINDOWS\system32> $VM="DEV999-test"

$spec.CpuHotAddEnabled = $true
$spec.MemoryHotAddEnabled = $true
$VM.ExtensionData.ReconfigVM($spec)

You can't use the OBN feature when calling vSphere API.
Change the 1st command to

 

$VM = Get-VM -Name "DEV999-test"
