Debug fails in python jupyter notebook where cells have `execution_count: null`

Bắt đầu bằng cách tái hiện lỗi với một notebook chứa một ô có execution_count là null, sau đó lần theo quá trình chạy qua debugpy/server/cli.py và pydevd_runpy.py như trong báo cáo. Hoàn thành có nghĩa là một notebook như vậy có thể được khởi chạy để debug mà không gặp NameError do giá trị null của JSON gây ra.

I have notebooks which have cells having the json attribute "execution_count" set to null.
This is common with tools, such as nbdev-clean which attempt to reduce diff-noise when saving notebooks in source control.

Unfortunately, it seems to make it impossible to debug in such notebooks from within VS Code's Python extension.

Here is a trace:
