cn_dissertation_1st_page.pdf
In trying to analyze the attached file with

    result = md.convert(file_path)
    return result.text_content

I got the following error

I am running it on Python 3.10 in MacOS 15.2 (24C101)

atter consulting with o1 and tinkering with it. I realize that it is because I am using pymupdf to reconstruct the pdf page and thus missing this meta info.
