Error while reading bookmarks/outlines "TypeError: argument of type 'NoneType' is not iterable" #1059
Description
"TypeError: argument of type 'NoneType' is not iterable"
Got this when I tried to read the outlines of a PDF file with PdfReader.outlines.
Environment
Which environment were you using when you encountered the problem?
$ python -m platform
Windows-10-10.0.19044-SP0
$ python -c "import PyPDF2;print(PyPDF2.__version__)"
2.4.1Code + PDF
Example PDF file: sample.pdf (Yes, you can use this file for tests)
from PyPDF2 import PdfReader
reader = PdfReader("sample.pdf")
print(reader.outlines)Traceback
