runpy.py Error

I am trying to use pipreqs on Python 3.9 on Win 10 and getting:

INFO: Not scanning for jupyter notebooks.

What is the problem here?
Thanks

Start with Main_Combinator_02.py and inspect line 15, where the traceback reports an IndentationError during ast.parse. Compare the surrounding indentation and rerun pipreqs; done means the file parses successfully and pipreqs can continue scanning it.
