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',
    },
  }
});

I had same problem, The problem is openssl.cnf file.
My operating system is Debian 10.
Try the following steps
Step 1: Go to /etc/ssl/openssl.cnf

Step 2: Find the following line and comment it.

# System default
openssl_conf = default_conf 

Step 3: Restart your node server
