Lock azure resource with PowerShell - azure

Question

I've been trying to run a script to create a lock on azure resource to prevent resources being deleted inadvertently.
I get an error message and I can't figure out why it's showing me this error message.
Script:
#Sign in to Azure account
Login-AzAccount
#Select the subscription you want to work on
Select-AzSubscription -Subscription "test.subscription"
#Get All Resources in a resource group
$Resources = Get-AzResource -ResourceGroupName dummy_rg | Format-Table
# Create lock "delete" on each Resource if it doesn't exist
foreach($Resource in $Resources) {
$ResourceName = $Resource.Name
$lck = Get-AzResourceLock -ResourceGroupName $Resource.ResourceGroupName -ResourceName $ResourceName -ResourceType $Resource.ResourceType
if ($null -eq $lck)
{
Write-Host "$ResourceName has no lock"
New-AzResourceLock -resourceGroupName $rg -ResourceName $ResourceName -ResourceType $Resource.ResourceType -LockName "$ResourceName-lck" -LockLevel CanNotDelete -Force
Write-Host "$ResourceName has been locked"
}
else
{
Write-host "$ResourceName already locked"
}
}
Error message:

#Start logging
Start-Transcript -Path "C:\Windows\Logs\Lock - $(((get-date).ToUniversalTime()).ToString("yyyy-MM-dd_hh-mm-ss")).log" -Force
#Connect to Azure account
Login-AzAccount
#Select Azure subscription
Set-AzContext -Subscription "subscription_id_numbers"
#Deny rule on Azure Data Factory and Azure Machine Learning
$Resources = Get-AzResource | Where-Object {$_.Name -NotLike '*adf*' -and $_.Name -NotLike '*aml*'}
# Create lock "delete" on each Resource if it doesn't exist
foreach($Resource in $Resources) {
$ResourceName = $Resource.Name
$lck = Get-AzResourceLock -ResourceGroupName $Resource.ResourceGroupName -ResourceName $ResourceName -ResourceType $Resource.ResourceType
if ($lck -eq $null)
{
Write-Host "$ResourceName has no lock"
Set-AzResourceLock -ResourceGroupName $Resource.ResourceGroupName -ResourceName $ResourceName -ResourceType $Resource.ResourceType -LockName "$ResourceName-lck" -LockLevel CanNotDelete -Force
Write-Host "$ResourceName has been locked"
}
else
{
Write-host "$ResourceName already locked"
}
}
#Stop Logging
Stop-Transcript
This will loop on every ressources except azure data factory in the tenant and create a "delete" type lock to make sure resources aren't deleted inadvertently.
