Merging one of the pdfs is raising a ValueError. This happens since the release of PyPDF2-2..10.6.
The pdfs that are merged are owasp dependency check reports. Only one of them causes the exception. Note: this also happens when I only merge this specific PDF and not the other, working, PDFs.
Note: this is my first issue raised for PyPDF2. I've tried to include all the information required but am not familiar with the process. If anything's missing or invalid, let me know.
Environment
Python 3.9
Code:
from PyPDF2 import PdfFileMerger
if __name__ == '__main__':
pdf_file = 'path-to-file-that-exists.pdf'
merger.append(pdf_file)Code in PyPDF2 where it breaks:
