I am trying to set an IP pool to NSX-T with the following function code
Function Set-NSXTIPPool {
<#
.Synopsis
Creates an IP Pool
.DESCRIPTION
Creates a IP Pool with a number of required parameters. Supported IP formats include 192.168.1.1, 192.168.1.1-192.168.1.100, 192.168.0.0/24
.EXAMPLE
Set-NSXTIPPool -display_name "Pool Name" -allocation_start "192.168.1.2" -allocation_end "192.168.1.100" -cidr "192.168.1.0/24"
.EXAMPLE
Set-NSXTIPPool -display_name "Test Pool Name" -allocation_start "192.168.1.2" -allocation_end "192.168.1.100" -cidr "192.168.1.0/24" -dns_nameservers "192.168.1.1" -gateway_ip "192.168.1.1" -dns_suffix "evil corp"

I try to execute the function with the following syntax
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
To debug this, I add the following line and pipe the what support to be the dataset it is execution with out as json
$ip_pool | ConvertTo-Json | Set-Content -Path "$($ENV:Temp)\IPPooljsontemplate.json"
From what I can tell, one of the parameter is not being set, which I am assuming this is the root of the error
"subnets": [
{
"allocation_ranges": "",
"cidr": "192.168.31.0/24",
"dns_nameservers": "192.168.30.2",
"dns_suffix": "tataoui.com",
"gateway_ip": "192.168.31.1"
}
]
Question is what am I missing? I am pretty sure the syntax usage is correct, I am totally green when it come to API call and function
