ValueError: invalid literal for int() with base 10: b'' #1270
Description
See #1269 for further details, this reports another issue I've come accross.
Environment
Which environment were you using when you encountered the problem?
$ python -m platform
Linux-5.4.0-122-generic-x86_64-with-glibc2.29
$ python -c "import PyPDF2;print(PyPDF2.__version__)"
2.10.3Code + PDF
This is a minimal, complete example that shows the issue:
import PyPDF2
with open("Introduction to Programming Using Python ( PDFDrive ).pdf", "rb") as f:
pdfreader = PyPDF2.PdfFileReader(f, strict=True)
metadata = pdfreader.metadataPDF file used above: Introduction to Programming Using Python ( PDFDrive ).pdf
Traceback
This is the complete Traceback I see:
