Pull request review from now deleted users raise en error


Here is an example of query (from a private repository) for a review that was created by a now deleted user

query PullRequestReview {
  node(id: "MDE3OlB1bGxSZXF1ZXN0UmV2aWV3NTQ4NzU2NA==") {
    ...on PullRequestReview {
      author {

It fails with a Something went wrong while executing your query message.

If I remove the author part, there is no error. Note that when I fetch the only comment of this review, the returned author is null. So I guess there is a problem here and the author of the review should also be null instead of raising an error :wink:
