[Bug]: challenge not supported action in aws_wafv2_rule_group, though docs indicate it is

[stevenwilliamson]

Terraform Core Version

v1.3.7

AWS Provider Version

v4.53.0

Affected Resource(s)

aws_wafv2_rule_group

Expected Behavior

The action block in a rule should support the challenge action as documented in the docs https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/wafv2_web_acl.html#challenge

Actual Behavior

Error reported that challenge block not expected

Error: Unsupported block type
│
│ on test.tf line 279, in resource "aws_wafv2_rule_group" "test":
│ 279: challenge {}
│
│ Blocks of type "challenge" are not expected here.

Changing the action type to captcha does work, and allows terraform to create the rule.

Creating the rule with action type captcha i can then change the action in the AWS console to challenge and the rule works as expected.

Relevant Error/Panic Output Snippet

      challenge {}
    }

    statement {
      not_statement {
        statement {
          geo_match_statement {
            country_codes = [
              "US", # USA
            ]
          }
        }
      }
    }

    visibility_config {
      cloudwatch_metrics_enabled = false
      metric_name                = "test"
      sampled_requests_enabled   = false

To follow up on this report i have just realised this is an inconsistency.

aws_wafv2_web_acl resource rules support actions allow, block, count, captcha, challenge

aws_wafv2_rule_group resource rules support allow, block, count, captcha but not challenge

AWS WAF Rule groups do however support the challenge response as it is possible to set this in the AWS console.

Just a heads up for those following this issue: I've made a PR to add support for challenge action to the rule groups

Feel free to add thumbs-up to it to try to get it released soon.
