Error on nodejs app running on heroku. (html-pdf)

I am using library html-pdf to render pdf and then send the file with email. It works like a charm on localhost

pdf.create(html, {format: 'A4'}).toFile(`./public/invoices/${order.id}.pdf`, (err, res) => {
            if (err) return console.log(err);
        });

Currently I'm hosting the nodejs on Heroku. It works fine until the pdf.create() executes. Getting this error:

I think the problem is in some of the html-pdf dependencies, like phantomjs. Would be glad if somebody could help me, or if someone knows about better html-pdf solution.

I actually found solution.

If anyone else wondering, just add

childProcessOptions: { env: { OPENSSL_CONF: '/dev/null' }

to options.

So it will look something like this

pdf.create(html, {/* ... */ childProcessOptions: { env: { OPENSSL_CONF: '/dev/null' }}).toFile(`./public/invoices/${order.id}.pdf`, (err, res) => {
            if (err) return console.log(err);
        });
