Terraform Configuration Files

resource "aws_wafv2_web_acl_logging_configuration" "example" {
  log_destination_configs = ["${aws_kinesis_firehose_delivery_stream.example.arn}"]
  resource_arn            = "${aws_wafv2_web_acl.example.arn}"
  redacted_fields {
    all_query_arguments { }
    uri_path { }
    method { }
    body { }
    query_string { }
  }
}

Expected Behavior

The data fields passed are selected on the AWS console as shown below:

Actual Behavior

Some fields are not present on the AWS Console and even the ones present do not seem to take effect - there's no error message - but also there's no effect. Also, the configurations are are identified as new changes each time "terraform plan" is run

Steps to Reproduce

1. terraform apply

Hi @jiwuh, thank you for reporting this issue! I can confirm this is definitely a bug in the provider when the redacted_fields block is configured with one of method , uri_path, or query_string as they are empty blocks {}. Please note that while our documentation indicates there are several fields supported within the redacted_fields configuration block and the WAFv2 API defines the block as https://docs.aws.amazon.com/waf/latest/APIReference/API_LoggingConfiguration.html and https://docs.aws.amazon.com/waf/latest/APIReference/API_FieldToMatch.html , only the 4 fields you see in the console are indeed valid attributes.In the linked PR, our documentation and the resource schema will reflect this.

In addition, in cases where you want to redact several fields like in the example you've provided, while the Provider will not error at plan-time, the redacted_fields block should only support one nested field at a time as the WAF API returns an error when more than 1 field is specified (not something I believe is documented well in the WAFv2 API docs). Thus do this, your example could be updated with:

resource "aws_wafv2_web_acl_logging_configuration" "example" {
  log_destination_configs = ["${aws_kinesis_firehose_delivery_stream.example.arn}"]
  resource_arn            = "${aws_wafv2_web_acl.example.arn}"

  redacted_fields {
    uri_path {}
  }

  redacted_fields {
    method {}
  }

  redacted_fields {
    query_string {}
  }
}

^^ This example, however, will only be doable with the proposed fixed in #14319 as we still have the issue where fields represented by the empty block {} are not picked up correctly w/in the provider.

Hope this helps clarify the discrepancy you are seeing between the Console and the Provider configuration! If you have any further questions, please let me know 😃
