I have a script that basically combines files into one PDF. Normally it works properly, but the last few days I have had the following failure and don't know where to start:

Uncaught exception

No other errors.

Any hidden setting that could help with this one?

Thank you for reporting this issue ❤️

I cannot reproduce this issue. As the code base has charged quite a bit, I'll close this issue.

Please let me know if you still see this in the latest PyPDF2 version!
