TypeError: xmpp.Iq is not a constructor

[JimLynchCodes]

Hello! I am trying to run the example file with node v10.19.0.

Here is my code:

var Superfeedr = require('superfeedr');

client = new Superfeedr("Eonjim", "[my_actual_password]");
client.on('connected', function () {

    console.log('connected!');
    client.subscribe("http://blog.superfeedr.com/atom.xml", function (err, feed) {

          console.log('subscribed!', feed);
    });
});

It seems to be successfully connected, but when trying to subscribe to any feed I just get the same error...

Here is the error output I'm seeing:

(node:78407) [DEP0107] DeprecationWarning: tls.convertNPNProtocols() is deprecated.

Any thoughts on what I'm doing wrong here?

Thanks! ♥️
