Auto Configuration Failed - libproviders.so: No such file or directory

I was trying to create to parse HTML to PDF Buffer in NodeJS using the following code...

pdf.create(html, { format: 'A4', header: { height: "5cm" }, footer: { height: '0.4cm' }, border: { left: '1cm', right: '1cm' } })
      .toBuffer((error, buffer) => {
          if (error) {
               console.log(error.stack)
               return res.status(500).json(null).end()
          }
}

But it returned this error:

Error: html-pdf: Unknown Error

The OS used to is Ubuntu Server 22.04
NodeJS = v16.15.0
html-pdf = v.3.0.1

It looks like the same issue of #563 from ZBilel but the difference is that the error log says libproviders.so: cannot open shared object file: No such file or directory

UPDATE: I found a solution by adding an option for pdf.create which is:

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

With this options the code will stay like this:

pdf.create(html, {/*...*/ childProcessOptions: { env: { OPENSSL_CONF: '/dev/null' } } } )
      .toBuffer((error, buffer) => {
          if (error) {
               console.log(error.stack)
               return res.status(500).json(null).end()
          }
}

Thanks to opengeekslabap answer on the issue #531.
