Quality analysis found the following errors: ### Problems 1. The API endpoint `POST /repos/{owner}/{repo}/issues` is expected to return a JSON response as mentioned in the bug report. 2. The "assignees" field in the expected JSON response should contain an array of assignees, but it currently only contains a single assignee. 3. The "closed_by" field in the expected JSON response should be null, as the issue is still open. However, it currently contains an assignee, which is incorrect. I would recommend explicitly noting the expected and observed behavior in the bug report. For example, "The 'assignees' field should contain an array of assignees, but it currently contains a single assignee."
