Appengine VSCode не может отлаживать Python main.py

Question

Я пытаюсь заставить VSCode отлаживать скрипт Google Appengine. Я следовал специальным инструкциям на веб-сайте VSCode для Pythong Appengine Debugging, где я запускаю процесс сборки. Затем я присоединяю отладчик к удаленному сеансу. Всякий раз, когда я присоединяюсь, я получаю эти ошибки. Стек вызовов и боковая панель отладки остаются пустыми.

Ошибка:
