How to delete submission comment?

[stevenagy]

Hi,

I've been trying to use the Python API to delete submission comments (e.g., when my autograding needs a "fresh" start with all previously-updated scores/comments deleted). While I could not find a suitable Python call for this, I attempted to use the requests API detailed here: https://canvas.instructure.com/doc/api/submission_comments.html#method.submission_comments_api.destroy.

However, it does not work as there is no comments field in the resulting form data, despite my having put multiple "Test" comments there:

{
  "id": (redacted),
  "body": null,
  "url": null,
  "grade": "100",
  "score": 100,
  "submitted_at": null,
  "assignment_id": (redacted),
  "user_id": (redacted),
  "submission_type": null,
  "workflow_state": "graded",
  "grade_matches_current_submission": true,
  "graded_at": "2024-07-19T00:11:05Z",
  "grader_id": (redacted),
  "attempt": null,
  "cached_due_date": "2024-09-20T05:59:59Z",
  "excused": false,
  "late_policy_status": null,
  "points_deducted": null,
  "grading_period_id": null,
  "extra_attempts": null,
  "posted_at": "2024-07-18T23:19:25Z",
  "redo_request": false,
  "custom_grade_status_id": null,
  "sticker": null,
  "late": false,
  "missing": false,
  "seconds_late": 0,
  "entered_grade": "100",
  "entered_score": 100,
  "preview_url": "https://utah.instructure.com/courses/(redacted)/assignments/(redacted)/submissions/(redacted)?preview=1&version=4"
}

Can someone please advise me on the best way to "wipe" previous submission comments?
