Exit 1 with binary version 0.12.6-1

[Goldziher]

Hi there,

I recently tried switching between version 0.12.5-1 (2018) to 0.12.6-1 (2020) of the binary (using this link to download it: https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.buster_amd64.deb), but this appears to cause an issue with the library:

  File "/usr/local/lib/python3.9/site-packages/wkhtmltopdf/utils.py", line 146, in wkhtmltopdf
    return check_output(ck_args, **ck_kwargs)
  File "/usr/local/lib/python3.9/subprocess.py", line 424, in check_output
    return run(*popenargs, stdout=PIPE, timeout=timeout, check=True,
  File "/usr/local/lib/python3.9/subprocess.py", line 528, in run
    raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['wkhtmltopdf', '--encoding', 'utf8', '--footer-html', '/tmp/tmpwf34m2lm.html', '--header-html', '/tmp/tmpjhuavkdp.html', '--page-size', 'A4', '--print-media-type', '/tmp/tmpio80hqhf.html', '-']' returned non-zero exit status 1.

It does work with the older version.

Same problem here downgrading to the 0.12.5-1 (2018) worked

@Goldziher i got this issue working with Docker and latest wkhtmltopdf 0.12.6.1-3 - i found that i needed to pass the correct domain, because my docker image tried to access localhost and wasn't able to get the correct static files -> therefor the error.

had some stuff like

 <link rel="stylesheet" type="text/css" href="{{ domain }}{% static 'css/pdf.css' %}">

in my templates

(tested it building the html by hand in the docker shell and trying to directly use wkhtmltopdf binary)

My Setup:

• python3.12-slim-bookworm
• wkhtmltopdf 0.12.6.1-3
• django 5.1.3

I'm still not sure about your solution. I had already solved the problem with the localhost with a second environment variable. (In Kubernetes there can be problems resolving the hostname to itself.)

Have you tried to start the server not with python manage.py runserver 0.0.0.0:8000 but with: gunicorn wsgi:application -b 0.0.0.0:8000?

With gunicorn I still get the same error. But if I only change the command in entrypoint.sh it works without problems.

exec python manage.py runserver 0.0.0.0:8000
->
exec gunicorn wsgi:application -b 0.0.0.0:8000

But if I try to get the static files into docker with wget this works without problems. So the static files are served correctly by django.

wget localhost:8000/static/some-file.css

It also works if I execute the wkhtmltopdf command via the bash and the export html in the container. (/tmp/wkhtmltopdf{asd}.html)

It is strange.

@MarcelHaldimann as mentioned via email -> also with gunicorn and serving staticfiles via whitenoise i get it working with the code in our repository

So i think the error is related to your setup
