- A bug was introduced in
  https://gitlab.com/gitlab-org/gitlab/-/merge_requests/50951
  with addition of `Array.wrap`, which caused return value of
  `GraphqlExtractor`, an enumerator, to be wrapped in an Array,
  which caused exception to be raised in `HashKeyDigger`
- Update return value of `GraphqlExtractor` to be original hash
  instead of wrapping it in an enumerator, there is no need for it
