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

[wmurphy126]

paperetl is great and has been useful for my work! It has been working well for most of the PDF papers I feed it. I am having some issues with certain PDFs. I am new to python, so its very likely I am doing something wrong but I thought I'd reach out.

When I run this for a specific PDF:

python3.10 -m paperetl.file /home/bill/brokenone /home/bill/brokenone /home/bill/brokenone

I get this error:
