TypeError from node in sphinx\domains\std.py process_doc() returning NoneType

[jkwphysics]

Describe the bug

I'm unable to build an existing project (which was created on an older version of sphinx) due to the type error. I've tried downgrading the package to 3.5.1 but the problem seems to persist. I have also upgraded to latest sphinx without success.
