Unable to query info for issues in Projects

[nashafa]

Hi. I'm running into a problem where I am unable query titles, ids, etc. for items in projects that are issues. I have not tested with pull requests, but I am able to query info for draft issues.

For example, the following GraphQL query works fine in the GitHub GraphQL API Explorer and with gh api (filling in a valid ProjectV2Item's node_id).

query GitHubProjectItemQuery($node_id: ID = "") {
  node(id: $node_id) {
    ... on ProjectV2Item {
      content {
        ... on DraftIssue {
          title
        }
        ... on Issue {
          title
        }
        ... on PullRequest {
          title
        }
      }
    }
  }
}

This is the equivalent I am using in Go.

var GitHubProjectItemQuery struct {
  Node struct {
    ProjectV2Item struct {
      Content struct {
        DraftIssue struct {
          Title string
        } `graphql:"... on DraftIssue"`
        Issue struct {
          Title string
        } `graphql:"... on Issue"`
        PullRequest struct {
          Title string
        } `graphql:"... on PullRequest"`
      }
    } `graphql:"... on ProjectV2Item"`
  } `graphql:"node(id: $node_id)"`
}
variables := map[string]interface{}{
  "node_id": githubv4.ID(node_id),
}
err := githubClient.Query(context.Background(), &GitHubProjectItemQuery, variables)

Oddly, for draft issues, the title appears in GitHubProjectItemQuery.Node.ProjectV2Item.Content.DraftIssue.Title, GitHubProjectItemQuery.Node.ProjectV2Item.Content.Issue.Title, and GitHubProjectItemQuery.Node.ProjectV2Item.Content.PullRequest.Title. For issues, nothing appears for any title, id, etc.

Any ideas as to what exactly is going on here? Thanks for the help.
