Hello guys,

I have just trying to move from python 3.7 to pythhon 3.9 and now, i get an error with django-wkhtmltopdf when i generate a PDF:

Traceback (most recent call last):

subprocess.CalledProcessError: Command '['wkhtmltopdf', '--encoding', 'utf8', '--quiet', '/tmp/wkhtmltopdfbb5l238z.html', '-']' died with <Signals.SIGSEGV: 11>.

It seems to come from rendered_content.

I use wkhtmltopdf 0.12.6

All work fine with 3.7

@thomasphilibert from the stack trace it looks like the call to wkhtmltopdf is failing. I am not sure why it would be any different between between Python 3.7 and 3.9.

Since it works with 3.7 we can assume that wkhtmltopdf is working correctly on your system. Is it possible for you to try calling wkhtmltopdf from a Python 3.9 script to see if that works?
