tlssock._start is not a function when trying to use nodemailer

[dehrhard]

Describe the bug
I'm trying to use nodemailer for an email service. createTransport works but if I try to call transport.sendMail. I receive the Error: Error initiating TLS - tlssock._start is not a function.
It looks like it happens in nodemailer when it tries to upgrade the connection in _upgradeConnection. In there it is calling tls.connect where tls is the native node module.
So it looks like the _start function is not polyfilled

Steps to Reproduce

1. Create Transport

import { createTransport } from 'npm:nodemailer';
const transport = createTransport({
  host,
  port,
  auth: {
    user,
    pass,
  },
});

2. try to send mail

transport.sendMail({
  to: '',
  from: '',
  ...
})

3. Error:

Failed in send Mail procedure
 Error: Error initiating TLS - tlssock._start is not a function

Expected behavior
I would expect sendMail to correctly work as expected in node

Environment
