After upgrading to Debian 10, html-pdf stopped working. That's because phantomjs, used by html-pdf fails when parsing /etc/ssl/openssl.cnf

This is the error when trying to run the example test that will generate the businesscard.pdf:

Setting that config file to an empty file solves the problem, but this is obviously not a long-term solution:

TAP version 13
# allows custom html and css
ok 1 null
ok 2 Returns the filename
ok 3 Saves the file to the desired destination

1..3
# tests 3
# pass  3

# ok

The default /etc/ssl/openssl.cnf file with debian 10 is:

# OpenSSL example configuration file.
# This is mostly being used for generation of certificate requests.
#

# Note that you can include other files from the main configuration
# file using the .include directive.

# defined.

Hi, I have this same issue running on this environment :

os : Ubuntu 18.04.3 LTS
node : v8.10.0
html-pdf : latest

but I don't have this line inside /etc/ssl/openssl.cnf file

# System default
openssl_conf = default_conf

Same problem here.
If you don't want (or can't) override your OpenSSL system configuration, you can use OPENSSL_CONF env var to load a custom config file without openssl_conf parameter

cp  /etc/ssl/openssl.cnf /tmp/html-pdf-openssl.cnf
sed -i '/openssl_conf/d' /tmp/html-pdf-openssl.cnf
OPENSSL_CONF=/tmp/html-pdf-openssl.cnf html-pdf test/businesscard.html businesscard.pdf

This issue persists on Ubuntu 21.04 and like the other person mentioned...

Two years later, the problem persists in Debian 11. Exact same error. Is this package being maintained?

The issue still persists. Any drop-in replacement available for html-pdf ?

I guess we need to move on from this lib to another solution to generate PDF. Any thought? Do you know a better approach to tackle this issue - Generating pdf from html in NodeJS - with less pain @cypx @DigitalLeaves @pigeonvictor @Franckapik @jscul

I am even thinking about using other languages to do that for me. Thanks.

Hey, are there any side effects using this option?
