Attempting to create AKS using terraform,resulting in unexpected behaviour

Question

terraform {
  backend "azurerm" {
   resource_group_name   = "storage"
   storage_account_name  = "statefile"
   container_name        = "state"
   key                    = "terraform_local.tfstate"
}

}
data "azurerm_client_config" "current" {}

provider "azurerm" {
   features {}
}

# Create a resource group
resource "random_pet" "rg_name" {
  prefix = var.resource_group_name_prefix
}

#create a resource group
resource "azurerm_resource_group" "rg" {
  name     = random_pet.rg_name.id
  location = var.resource_group_location       
 }

resource "azurerm_kubernetes_cluster" "cluster" {
  name                = "learnk8scluster"
  location            = azurerm_resource_group.rg.location
  resource_group_name = azurerm_resource_group.rg.name
  dns_prefix          = "learnk8scluster"

  default_node_pool {
  name       = "default"
  node_count = "2"
  vm_size    = "standard_d2_v2"
}

 identity {
  type = "SystemAssigned"
 }
}

I'm attempting to create a simple AKS cluster within a resource group. However when I run terraform init, plan and apply I get the following:

Error: creating Kubernetes Cluster │ Resource Group Name: "rg-rational-monkfish" │ Kubernetes Cluster Name: "learnk8scluster": polling after CreateOrUpdate: result.Status was nil/empty - op.Status was "ProvisionNetworkResources" / op.Properties.ProvisioningState was ""

It's created in my azure portal, However it's not within the state file.

Unexpected behaviour while to creating AKS using terraform

This kind of provisioning issues are quit offen itseems due to a transient issue or a misconfiguration.

As per the terraform registry it is seems that

When i checked using eastus2, centralus, eastasia, westcentralus, uksouth, eastus location all able working fine from this morning.

When I checked i was able to provision the resource across different locations.

Demo configuration:

terraform {
  backend "azurerm" {
    resource_group_name   = "vksb-rg"
    storage_account_name  = "fdadabhadkcajcjal"
    container_name        = "state"
    key                   = "terraformlocal.tfstate"
  }
}

data "azurerm_client_config" "current" {}


resource "azurerm_kubernetes_cluster" "cluster" {
  name                = var.aks_cluster_name
  location            = azurerm_resource_group.rg.location
  resource_group_name = azurerm_resource_group.rg.name
  dns_prefix          = var.aks_cluster_name

  default_node_pool {
    name       = "default"
    node_count = var.node_count
    vm_size    = var.vm_size
  }

  identity {
    type = "SystemAssigned"
  }

  tags = {
    environment = "test"
  }

  depends_on = [azurerm_resource_group.rg]
}
