I am trying to generate pdf of the order summary in my ecommerce website but receiving the following error.

OSError: wkhtmltopdf reported an error:

Exit with code 1 due to network error: RemoteHostClosedError

I am using flask as the webframework and here's the code:

    rendered = render_template("order-summary.html",
                               total_cost=total_cost,
                               name=name,
                               price=price)
    config = pdfkit.configuration(wkhtmltopdf=r'C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe')
    pdf = pdfkit.from_string(rendered, False, configuration=config)
    response = make_response(pdf)
    response.headers['Content-Type'] = 'application/pdf'
    response.headers['Content-Disposition'] = 'inline; filename=output.pdf'
    return response

I searched over the internet but didn't got anything relevant that solves the problem.

    See [this answer](https://stackoverflow.com/a/41700417/2052575) which suggests wkhtmltopdf is having trouble loading external URLs. In the context of your code, as you're using `pdfkit.from_string` this might suggest that there are URL's within the rendered `order-summary.html` which the server is having trouble loading (CSS/script imports perhaps). I'd try loading an HTML template which doesn't load external assets to rule that out. – v25 Jan 03 '21 at 13:32

Pass the external *.css file path used inside order-summary.html as agrument in from_string method. df = pdfkit.from_string(rendered, False, configuration=config, css=['./file1.css','./file2.css'])
