"separator" argument not works

[eking-go]

Hello.

Corresponding to https://github.com/aztfmod/terraform-provider-azurecaf#argument-reference I use:

resource "azurecaf_naming_convention" "vm_name" {
   name          = lower(local.name)
   prefix        = "vm"
   separator     = ""
   resource_type = "vml"
   max_length    = 64
   convention    = "passthrough"
}

But get error:

Error: Unsupported argument

  on main.tf line 52, in resource "azurecaf_naming_convention" "vm_name":
  52:   separator     = null

An argument named "separator" is not expected here.

Terraform - 0.12; version of azurecaf provider - 1.2.2

azurecaf_naming_convention it is deprecated please use azurecaf_name instead
