Python pdfminer TypeError: a bytes-like object is required, not 'str'

I am extracting text from a pdf file using pdfminer, and below is my code:

def parse(fname):
    fp = open(fname, 'rb')
    parser = PDFParser(fp)
    doc = PDFDocument(parser)
    parser.set_document(doc)
    rsrcmgr = PDFResourceManager()
    laparams = LAParams()
    device = PDFPageAggregator(rsrcmgr, laparams=laparams)
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    
    parsed = []
    
    for page in PDFPage.create_pages(doc):
        print(page)
        interpreter.process_page(page)
        layout = device.get_result()
        page = []
        pagebuffer = []
        flag = False
        
        for x in layout:
            if(isinstance(x, LTTextBox)):
                pagebuffer += [x.get_text()]
                
                if(x.get_text()[-1] == "\n"):
                    flag = False
                    page += pagebuffer
                    pagebuffer = []
                    
        parsed += [page]

    fp.close()
    return parsed 

This code works fine with one of my pdf files, I can successfully extract text, but while I tried to extract the other file, the error came:

Is there any idea what can I do for this situation?

Thanks a lot!
