Tái hiện ví dụ trong thư mục doc và bắt đầu từ notices_v1_red_get trong interpol/api/default_api.py, lần theo traceback qua api_client.py, model_utils.py và model/red_notices.py. Công việc hoàn tất khi request được ghi trong tài liệu không còn gây ra TypeError đã nêu và hoàn thành thành công.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
