Bug in aws_waf_web_acl resource - waf resource does not exist

[jeraldsm]

🎛 Inspec resource aws_waf_web_acl fails to detect resource even though they actually exist.

🌍 InSpec and Platform Version

InSpec client Version:5.18.14
inspec-aws Version: 1.83.43

🤔 Replication Case

We are trying to check whether the WAF resource exist in the AWS account using the inspec resource aws_waf_web_acl, but unfortunately the inspec execution fails as it does not detect the resource in AWS, even though the aws waf resource actually exists in EU-frankfurt region.

  ×  WebACLExists: WAF Web ACL Exists Tests (3 failed)
     ×  Web ACL ID: d88828c3-6c85-xxxx is expected to exist
     expected Web ACL ID: d88828c3-6c85-xxxx to exist
     ×  Web ACL ID: a9a5cb86-e31e-xxxx expected to exist
     expected Web ACL ID: a9a5cb86-e31e-xxxx to exist
     ×  Web ACL ID: a9793633-fd6a-xxxxis expected to exist
     expected Web ACL ID: a9793633-fd6a-xxxx to exist

Following is the ruby code for checking if the WAF exists:

# Input variables
content = inspec.profile.file("attributes.json")
params  = JSON.parse(content)

# Get json values
aws_waf_web_acl_id    = params['web_acl_id']['value']

  # Controls
  control "WebACLExists" do
    impact 1.0
    title "WAF Web ACL Exists Tests"
    desc "Checking if the AWS WAF web ACLs has been successfully created"
    for element in aws_waf_web_acl_id
      describe aws_waf_web_acl(web_acl_id: element) do
        it { should exist }
      end
    end
  end

Here's the JSON file where the WAF ids are parsed.

  "web_acl_id": {
    "sensitive": false,
    "type": [
      "tuple",
      [
        "string",
        "string",
        "string"
      ]
    ],
    "value": [
      "d88828c3-6c85-xxxx",
      "a9a5cb86-e31e-xxxx,
      "a9793633-fd6a-xxxx"
    ]
  }

Is there something I can do to fix this? Any help will be appreciated.

This is happening because the v2 sdk is not supported yet.

For example for loadbalancing v2 has

https://github.com/inspec/inspec-aws/blob/main/libraries/aws_backend.rb

require "aws-sdk-elasticloadbalancing"
require "aws-sdk-elasticloadbalancingv2"

Waf only has 1.0 support

require "aws-sdk-waf"

...
def waf_client
    aws_client(Aws::WAF::Client)
  end
