Hi,
I am facing error while tying to sign document usign global sign DSS. I am getting below error

Error

File "test.py", line 4, in
document = HTML.render()
TypeError: render() missing 1 required positional argument: 'self'

Code

from weasyprint import HTML
from weasysign import factory

document = HTML.render()

subject_dn = {'subject_dn': {
"common_name": "Dunder Mifflin Paper Company, Inc.",
"organizational_unit": [
"Angela Martin",
"Accounting"
]
}}
signer = factory('globalsign', cfg_file='globalsign_config.ini', subject_dn=subject_dn)
document.write_pdf(target='/tmp/my-digitally-signed-doc.pdf', finisher=signer)

Environment

Python 3.8.12

Your syntax is incorrect. You are trying to call the render method on the class, not an instantiated object.
document = HTML().render()

Hi Eddie Zab,

Thanks for the response, is there any method in the library to sign an already existing PDF document, instead of rendering HTML file
