Terraform Configuration Files

The below code is a subset from the example usage given on the doc page at https://www.terraform.io/docs/providers/azurerm/r/web_application_firewall_policy.html I receive the same error using the full example from that page.

resource "azurerm_resource_group" "example" {
  name     = "example-rg"
  location = "West US 2"
}

resource "azurerm_web_application_firewall_policy" "example" {
  name                = "example-wafpolicy"
  resource_group_name = azurerm_resource_group.example.name
  location            = azurerm_resource_group.example.location

  custom_rules {
    name      = "Rule1"
    priority  = 1
    rule_type = "MatchRule"

    match_conditions {
      match_variables {
        variable_name = "RemoteAddr"
      }

      operator           = "IPMatch"
      negation_condition = false
      match_values       = ["192.168.1.0/24", "10.0.0.0/24"]
    }

    action = "Block"
  }
}

Do we know if this issue has been fixed yet ?

I just checked with the azurerm provider 2.0.0 and I am still seeing the same error message when I try to create this waf policy.

@robert-kopec Please follow #6126 for progress.

Any further ETA questions on this issue will not help speed up the progress.

This has been released in version 2.8.0 of the provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading. As an example:

provider "azurerm" {
    version = "~> 2.8.0"
}
# ... other configuration ...
