Using the explorer with the following query and variables I'm getting the below error how can I find out what service is unavailable.

GetProjectPullRequests_vars.txt
GetProjectPullRequests_query.txt

Any help apprecaited.

"errors": [
    {
      "type": "SERVICE_UNAVAILABLE",
      "path": [
        "repository",
        "pullRequests",
        "nodes",
        0,
        "commits",
        "nodes",
        0,
        "commit",
        "additions"
      ],
      "locations": [
        {
          "line": 84,
          "column": 15
        }
      ],
      "message": "The additions count for this commit is unavailable."
    }

From this error I can see an issue with the commit/additions part of the request so removing this and deletions now works.

But I need them so would like to understand the issued here.
