WAF OWASP 3.1 - RuleSet Version '3.1' does not support Per Rule Actions

Terraform Providers Azure
1

Hi Team,

I tried the below terraform code to create WAF 3.1 with rule group override.
But it throws error in Terraform whereas rule group override works fine in azure portal manually or using powershell and az commands.

resource “azurerm_web_application_firewall_policy” “testwafpolicy” {
name = “testwafpolicy1”
resource_group_name = “rg-weu-dev-cnryappgwapi-01”
location = “westeurope”

policy_settings {
enabled = false
file_upload_limit_in_mb = 100
max_request_body_size_in_kb = 128
mode = “Prevention”
request_body_check = true
}

managed_rules {
managed_rule_set {
type = “OWASP”
version = “3.1”
rule_group_override {
rule_group_name = “REQUEST-920-PROTOCOL-ENFORCEMENT”
rule {
id = “920300”
enabled = true
action = “Log”
}

    rule {
      id      = "920440"
      enabled = true
      action  = "Block"
    }
  }

}

exclusion {
  match_variable          = "RequestHeaderNames"
  selector_match_operator = "Equals"
  selector                = "x-some-header"

  excluded_rule_set {
  }
}

}
}

Error:
