html-pdf fails with Debian 10 due to new version of OpenSSL
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:

ok 1 null
ok 2 Returns the filename
ok 3 Saves the file to the desired destination

# pass 3

Same issue for me when migrating on Debian10. Your patch works fine !
Thank you !

Thank you, saved my day !
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
Any news on this ? I don't want to override my OPENSSL_CONF
This issue persists on Ubuntu 21.04 and like the other person mentioned...
# System default
openssl_conf = default_conf
...does not exist.
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.
Solution without devOps
- fixed SSL issue: simulate empty config https://github.com/bazelbuild/rules_closure/issues/351#issuecomment-1116945290
- html-pdf assept options for
childprocess
wich will be paseed into phantomJs - node_modules/html-pdf/lib/pdf.js:89 (childProcessOptions)
- https://nodejs.org/api/child_process.html
- added env object to childProcessOptions for overriding OPENSSL_CONF
pdf.create(html, {
childProcessOptions: {
env: {
OPENSSL_CONF: '/dev/null',
},
}
});
Solução sem DevOps
- problema de SSL corrigido: simular vazamentos de phantomjs de configuração vazios do sandbox bazelbuild/rules_closure#351 (comentário)
- html-pdf assept opções para
childprocess
as quais serão passadas em phantomJs- node_modules/html-pdf/lib/pdf.js:89 (childProcessOptions)
- https://nodejs.org/api/child_process.html
- adicionado objeto env a childProcessOptions para substituir OPENSSL_CONF
pdf.create(html, { childProcessOptions: { env: { OPENSSL_CONF: '/dev/null', }, } });
This worked for me!

Hey, are there any side effects using this option?
