Hey,

yesterday everything was working okay, but today i get this error when i try to send a video to one of my Samsung TVs:
(Everything is working for my other two Samsung TVs, and i didn't change anything...)

C:\Users\***\Documents\nodejs-projects\samsung-dlna\node_modules\upnp-device-client\index.js:571
    var value = node.findtext('./' + field);
                    ^

The error is blocking furher execution.

I wonder what is going on there.
It's neither working from my Windows PC nor my Raspberry Pi.
Even though, I can send videos per upnp from Windows Media Player to this TV...

Can you give me a hint what is going on there in the code?

This is my code by the way:

var MediaRendererClient = require('upnp-mediarenderer-client');
var options = {
    autoplay: true, //play immediately
    contentType: 'video/x-ms-wmv',
    metadata: {
        title: 'Tuer klingelt',
        creator: 'Smarthome',
        type: 'video' //, // can be 'video', 'audio' or 'image'
    }
};

var client = new MediaRendererClient('http://192.168.178.26:7676/smp_11_');
client.load('http://*****/img/doorbell.wmv', options, function (err, result)
{
    console.log(result);
    if (err) throw err;
    console.log('VIDEO SUCCESSFULLY SENT TO TV!');
});

@KenADev Did you ever solve it?

@KenADev Did you ever solve it?

I solved it somehow, but unfortunately, it's been over 5 years ago and I don't have the code anymore.
