Error: html-pdf: Unknown Error

[novilfahlevy]

I get this error on production (but works perfectly on local), I have been searching it and found a similar issues like these:
marcbachmann/node-html-pdf#531 (comment)
and
https://stackoverflow.com/questions/60966814/node-html-pdf-auto-configuration-failed

those issues above tell that the problem was about the the ssl but I still don't understand it.

My code:

My os specifications:
Distributor ID: Ubuntu
Description: Ubuntu 22.04 LTS
Release: 22.04

nginx version: nginx/1.18.0 (Ubuntu)

i got the same problem on production using heroku. The solution for me was creating a new env var OPENSSL_CONF with value /dev/null.

i added to heroku env vars and it worked for me.

Ran into this problem while prototyping on WSL / Debian (Windows Subsystem for Linux) and a common solution from OP's stack overflow hit worked: edit /etc/ssl/openssl.conf and comment out the openssl_conf = default_conf line.
