  • Can you share the entire error page to get more info? In any case, the error says that your are passing a string, not a file to read. Maybe you can solve it just adding this: response['Content-Transfer-Encoding'] = 'binary' – LaCharcaSoftware Feb 21 '22 at 10:54
  • Do you want to download a pdf file from your server or do you want to convert the web page to a pdf file and download it? – Sandil Ranasinghe Feb 21 '22 at 11:28
  • Of course, because you are not using FileWrapper function in a right way. You are passing just a string with a filename to FileWrapper. This has no sense. What exactly is the content of your PDF? You can find some examples of FileWrapper here: https://www.programcreek.com/python/example/78219/wsgiref.util.FileWrapper – LaCharcaSoftware Feb 21 '22 at 11:29

You can convert a HTML page to a PDF on-the-fly and send its result as a response in Django with Django Weasyprint. E.g., have a look at the examples with WeasyTemplateResponseMixin.
