Terraform Configuration Files

resource "azurerm_kubernetes_cluster_node_pool" "application" {
  count                 = var.multi_np_flag ? 1 : 0
  name                  = "application"
  mode                  = "User"
  kubernetes_cluster_id = azurerm_kubernetes_cluster.cluster.id # This id is forcing the recreation

  tags                  = var.standard_tags
  node_labels           = { "kroger/node-type" : "application" }
  lifecycle {
    ignore_changes = [
      node_count
    ]
  }
}

Debug Output

Panic Output

Expected Behaviour

Terraform should not be recreating the node pool or provide a migration for the changed id.

Actual Behaviour

The state has: kubernetes_cluster_id = "/subscriptions/xxx/resourcegroups/rg6744galactusk8dev/providers/Microsoft.ContainerService/managedClusters/galactus-cluster-dev-aks"

But has changed to: kubernetes_cluster_id = "/subscriptions/xxx/resourceGroups/rg6744galactusk8dev/providers/Microsoft.ContainerService/managedClusters/galactus-cluster-dev-aks"

Note the resourcegroups -> resourceGroups change. Perhaps this was updated in a version?

Steps to Reproduce

1. terraform plan
