Hello

I am trying to create a custom rule, that should match if a parameter I pass match the format for a subnet.
The parameter is an array. I am wondering if I am using it wrong, or this is something that is no support for yet

I have tested with a string, and that seems to work.

The parameter looks like this:
"Subnets": [
"172.16.0.0/24",
"172.16.1.0/24"
],

And the Rule looks like this
`

apiVersion: github.com/microsoft/PSRule/v1
kind: Rule
recommend: "VPN Local gateways onPremise network should be a subnet"
metadata:
name: "Local.YAML.localNetworkGateways.Subnet"
spec:
type:
- "Microsoft.Network/localNetworkGateways"
condition:
allOf:
- field: "properties.localNetworkAddressSpace.addressPrefixes"
isArray: true
- field: "properties.localNetworkAddressSpace.addressPrefixes"
match: '(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)/([1-3][0-2]$|[0-2][0-9]$|0?[0-9]$)'
