What happened? What were you trying to achieve?
I am trying to read text from a pdf file. But I am getting an error which I don't think is because of my code. The code crashes for the particular pdf mentioned below.

Environment

Which environment were you using when you encountered the problem?

$ python -m platform
Windows-10-10.0.22000-SP0

$ python -c "import PyPDF2;print(PyPDF2.__version__)"
2.10.9

Code + PDF

This is a minimal, complete example that shows the issue:

    if afile.endswith(".pdf"):
        pdfReader = PyPDF2.PdfFileReader(open(afile, "rb"), strict=False)
        texts = pdfReader.getPage(0).extract_text() # the ERROR happens on this line !!!!!
        for kw in keywords:
            if kw not in texts: return False
            # pbar.write(f'{kw} found')
        return True

don't add them to your tests!
