When trying to clone certain pdf documents, an "AttributeError: 'TextStringObject' object has no attribute '_clone'" appears. This problem happens consistently with the same "AttributeError: 'TextStringObject'.

Environment

Which environment were you using when you encountered the problem?

$ python -m platform
# Windows-10-10.0.19045-SP0

$ python -c "import pypdf;print(pypdf.__version__)"
# 3.4.1

Code + PDF

# TODO: Your code goes here
`   
    # Read the file
    reader = PdfReader(in_file_path, strict = False) # strict = False
    file_name = os.path.basename(in_file_path) # get file name of pdf
    
    # Open a writer file and clone
    writer = PdfWriter()
    writer.clone_document_from_reader(reader) # FAILS IN THIS METHOD
`
