[BUG][GraphQL] When fetching PRs via GraphQL (v4) PRs of actions does not return Issuer

Hi!

I try to use the github graphql api to fetch pull requests. When doing so I rely on the Issuer object to get some statistics.
It seems that when a github action opens a PR then the returned issuer is an empty object, instead of the bots github id.
This field does return when using the Rest api V3 :slight_smile:
Would like to know if this is indeed an issue or a wrong usage of mine?

Here is my GraphQL request for reference

  repository(owner: $owner, name: $repo_name) {{

        endCursor
