Status of newly created subnet does not change in powershell

Question

I have the following code to create a subnet in an existing address space, 10.1.2.0/24. The subnet is created in the console after a minute but the response is stuck in the while loop. How can I resolve this?

$vnet = Get-AzVirtualNetwork -Name $vnetName -ResourceGroupName $resourceGroupName

$subnet = @{
    Name = 'newsubnet1'
    VirtualNetwork = $vnet
    AddressPrefix = '10.1.2.32/28'
}

$subnetConfig = Add-AzVirtualNetworkSubnetConfig @subnet
$vnet | Set-AzVirtualNetwork | Out-Null

while ($null -eq $subnet.Id) {
    Write-Log "Waiting for subnet1 to be fully provisioned..."
    Start-Sleep -Seconds 10
    $subnet = Get-AzVirtualNetworkSubnetConfig -Name "newsubnet1" -VirtualNetwork $vnet
}

Thank you for reaching out.

I tried the script on my end and ran into same issue, I think it will help if you could report this issue on the Azure PowerShell Repository here

Meanwhile you can follow the script below as a workaround, where I have invoked Subnets - Get REST API to fetch the subnet provisioning state after the subnet is deployed.

Connect-AzAccount
$SubId = "SubID"
Set-AzContext -Subscription $SubId

$vnetName="vnetName"
$resourceGroupName="resourceGroupName"
$subnetName = "subnetName"
$url = "https://management.azure.com/subscriptions/"+$SubId+"/resourceGroups/"+$resourceGroupName+"/providers/Microsoft.Network/virtualNetworks/"+$vnetName+"/subnets/"+$subnetName+"?api-version=2022-11-01"

$token = (Get-AzAccessToken).token

$headers = @{'Authorization' = "Bearer $token"}

$vnet = Get-AzVirtualNetwork -Name $vnetName -ResourceGroupName $resourceGroupName

$subnet = @{
    Name = $subnetName
    VirtualNetwork = $vnet
    AddressPrefix = '10.0.47.32/28'
}

$subnetConfig = Add-AzVirtualNetworkSubnetConfig @subnet
$vnet | Set-AzVirtualNetwork | Out-Null

$result = Invoke-WebRequest -Method GET -Uri $url -Headers $headers -UseBasicParsing

$body = $result.Content | ConvertFrom-Json

$ProvState = $body.properties.provisioningState
If ($ProvState -eq "Succeeded")
{
Write-Output "Provisioning successfull"
}

else
{

While ($ProvState -ne "Succeeded")
{
Start-Sleep -Seconds 10
$result = Invoke-WebRequest -Method GET -Uri $url -Headers $headers -UseBasicParsing

$body = $result.Content | ConvertFrom-Json

$ProvState = $body.properties.provisioningState
}
}

Hope this helps! Please let me know if you have any questions. Thank you!
