object reference not set for setting IP Pool

[dwchan69]

I copy just the "Function Set-NSXTIPPool {}" portion of the code within in mine, as it seems pretty straight forward. When I try to execute the following,

Set-NSXTIPPool -display_name "Test Pool Name" -allocation_start "192.168.31.2" -allocation_end "192.168.31.100" -cidr "192.168.31.0/24" -dns_nameservers "192.168.30.2" -gateway_ip "192.168.31.1" -dns_suffix "tataoui.com" -Confirm:$false

here is the error I am getting.

Object reference not set to an instance of an object. At line:124 char:17

•             $NSXTIPPoolService.create($ip_pool)
  

•             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  

  • CategoryInfo : OperationStopped: (:) [], CisException
  • FullyQualifiedErrorId : VMware.VimAutomation.Cis.Core.Types.V1.CisException

I walk through the code and not sure what else I am not setting prior or missing

I pipe the $ip_pool variable out to a json prior to executing $NSXTIPPoolService.create($ip_pool)

I think I find the problem, but not sure why. The IP allocation range is not being set for some reason?
