AttributeError: 'NoneType' object has no attribute '__code__'

When running the following self-contained example I'm hit with an AttributeError

Traceback (most recent call last):
  File "/home/user/env/lib/python3.11/site-packages/jurigged/codetools.py", line 493, in _process_child_correspondence

AttributeError: 'NoneType' object has no attribute '__code__'

Any idea of what could be going wrong?

import asyncio
from pathlib import Path

import jurigged


async def slave():
    try:
        print('hello there')
        print("starting A")
        while True:
            print("A")
            await asyncio.sleep(1)
    except asyncio.CancelledError:
        print("stopped A")


async def master(tg: asyncio.TaskGroup):
    while True:
        task = asyncio.create_task(slave())
        await asyncio.sleep(4)
        task.cancel()


async def main():
    async with asyncio.TaskGroup() as tg:
        tg.create_task(master(tg))


if __name__ == "__main__":
    jurigged.watch(str(Path.cwd() / "asynctgtest.py"))
    asyncio.run(main())

What seems to happen is that the codefind module collects function codes first when it is loaded (when import jurigged happens), and then when new files are imported. The functions in asynctgtest.py are therefore not picked up, because they are defined after the collection, but also after the file is imported.

I'll try to come up with a proper solution (and maybe a better error message), but in the meantime you can move import jurigged after the definition of main and it should work.
