I need some help with setting Advanced Networking for azurerm_kubernetes_cluster

I've been using code from this page as an example https://www.terraform.io/docs/providers/azurerm/r/kubernetes_cluster.html

The only difference is that I make a module from it for my purpose. All there rest is pretty the same

Problem is with

network_profile {
    network_plugin = "azure"
  }

After run terraform plan I received the error below:

Error: module.aks.azurerm_kubernetes_cluster.aks: : invalid or unknown key: network_profile

I will be glad for any help thx

Update:

Terraform v0.11.8
+ provider.azurerm v1.5.0          <---- Wrong version, should be v1.15.0
