Terraform Version

1.2.0

AzureRM Provider Version

3.8.0

Affected Resource(s)/Data Source(s)

data azurerm_private_dns_zone

Terraform Configuration Files

terraform {
  required_providers {
    azurerm = {
      source                = "hashicorp/azurerm"
      version               = "=3.8.0"
      configuration_aliases = [azurerm, azurerm.ops]
    }
  }
}

data "azurerm_private_dns_zone" "aks-dns-zone-lookup" {
  name                = "privatelink.eastus.azmk8s.io"
  provider            = azurerm.ops
}

output "testing" {
  value = data.azurerm_private_dns_zone.aks-dns-zone-lookup.id
}

Debug Output/Panic Output

testing = "/subscriptions/***/resourceGroups//providers/Microsoft.Network/privateDnsZones/privatelink.eastus.azmk8s.io"

Expected Behaviour

testing = "/subscriptions/***/resourceGroups/my-resource-group-name-here/providers/Microsoft.Network/privateDnsZones/privatelink.eastus.azmk8s.io"

In v3.7.0, the resource group name was optional on the data lookup, but in v3.8.0 it returns an id without the resource group name in the path if a resource group name is not provided. Adding the resource group name to the data lookup includes the resource name, indicating that it's now required in 3.8.0 or a regression was introduced in 3.8.0.

Actual Behaviour

testing = "/subscriptions/***/resourceGroups//providers/Microsoft.Network/privateDnsZones/privatelink.eastus.azmk8s.io"

The resource group name is excluded in 3.8.0, while it was previously included in 3.7.0

Steps to Reproduce

terraform apply

@jdaugherty - looks like this was a byproduct of #16858. In prior versions, the resource ID was lazily generated (off of the Azure API response). But after the move to the embedded SDK, the ID was eagerly generated.

And while the resource group name attribute in the state was always being populated, the resource group name attribute on that ID wasn't updated if/when omitted in the configuration.
