TypeError: Arguments to path.join must be strings NodeJS

I'm creating a simple web API using NodeJS express, for some home domotics. For my TV I'm using the following library --> https://github.com/hobbyquaker/lgtv2.

When I run my code locally, for example;

        var lgtv = require('lgtv2')({
        url: 'ws://192.168.178.31:3000'
    });

    lgtv.on('error', function(err) {
        console.log(err);
    });

    lgtv.on('connect', function() {
        console.log('connected');
        lgtv.request('ssap://system/turnOff', function(err, res) {
            lgtv.disconnect();
        });

    });

It run's fine. However, the same code, deployed to my Synology NAS, results in an error.

TypeError: Arguments to path.join must be strings

The only actual difference I can spot is the NPM version, which is v10.14.1 locally and v0.10.48 on my NAS. Is there any way to bypass this problem and get this working?

It is very strange library.

Try this code

console.log('Platform = ',process.platform);
var lgtv = require('lgtv2')({
    url: 'ws://192.168.178.31:3000',
    clientKey: ''
});

lgtv.on('error', function(err) {
    console.log(err);
});

lgtv.on('connect', function() {
    console.log('connected');
    lgtv.request('ssap://system/turnOff', function(err, res) {
        lgtv.disconnect();
    });

});
