Terraform Configuration Files

resource "azurerm_application_gateway" "network" {
...
  request_routing_rule {
    name               = "rrrule"
    rule_type          = "PathBasedRouting"
    http_listener_name = "httplistener"
    url_path_map_name  = "urlmap"
  }

  redirect_configuration {
    name          = "redirectrule"
    redirect_type = "Permanent"
    target_url    = "https://example.com"
  }

  url_path_map {
    name                               = "urlmap"
    default_backend_address_pool_name  = "backend1"
    default_backend_http_settings_name = "backendhttpsetting1"

   path_rule {
      name                       = "paths1"
      paths                      = ["/redirect"]
      redirect_configuration_name = "redirectrule"
    }
  }
}

Expected Behavior

This should create a path based request routing rule with a default backend and a redirect rule.

Actual Behavior

This is actually creating the application gateway as expected, but since there is a validation inside the flatten function the read function fails.
I think that checking for redirect_configuration_name and default_backend_address_pool_name is not right, since those two parameters are not mutually exclusive.

Steps to Reproduce

1. terraform apply
