wkhtmltopdf exited with non-zero code -6. error: QXcbConnection: Could not connect to display

Please help

Please add virtualization

Your account already has the new virtualisation system. What code are you using that generates that error?

def generate_PDF(request, id, customer, invoice_no):

pdf = pdfkit.from_url(request.build_absolute_uri(reverse('invoice-detail', args=[id])), False)

response = HttpResponse(pdf, content_type='application/pdf')
filename = customer + "_" + invoice_no + ".pdf"
response['Content-Disposition'] = 'attachment; filename="%s"' % filename

return response

Above code is working perfectly in local environment , not working in pythonanywhere

have you seen something like this?

above is the error log now

def generate_PDF(request, id, customer, invoice_no): # Use False instead of output path to save pdf to a variable

display = Display(visible=0, size=(1024, 768))
try:
   display.start()
   pdf = pdfkit.from_url(request.build_absolute_uri(reverse('invoice-detail', args=[id])), False)
   response = HttpResponse(pdf, content_type='application/pdf')
   filename = customer + "_" + invoice_no + ".pdf"
   response['Content-Disposition'] = 'attachment; filename="%s"' % filename
finally:
   display.stop()
return response

All code is running from webapp , i need to convert one html page to pdf , that needs connection to my own site .

I see that you posted in another forum thread about this, so let's continue the conversation there.
