Javascript SDK for Smart view does not work!

Smart TV
1

Downloaded the package from -> https://developer.samsung.com/smarttv/develop/extension-libraries/smart-view-sdk/download.html

I get an error when I try to import the msf-2.3.4.min.js file which comes in that package. Trying to implement just the basic code to discover TV in my network.

Code ->

msf.search(function(err, services){
    if(err) return console.error('something went wrong', err.message);
    console.log('found '+services.length+' services');
});

Error in console ->

Cannot read property '1' of null at RTCPeerConnection.n.onicecandidate

Please help if you know any other way to connect to my app using javascript API’s

Thank you

Did you solve the problem? I have the similar issue with msf-2.3.4.min.js
When I run

	var search = msf.search();
	search.on('found', function(services) {
		for (var i = 0; i < services.length; i++) {
			console.log('Found service ' + services[i].name);
			alert(services[i].name);
		}
	});
	search.start();

on emulator - nothing happens.
Run on the device SM-R800 (galaxy watch) cause error
Uncaught (in promise) DOMException: Failed to set local offer sdp: Failed to create channels.

version msf-2.0.22.min.js does nothing for emulator and for device.

I have the same issue. The error is caused by the IP address parsing snippet below:

// Line below is from source map: msf://lib/util/Search.js line 54
    pc.onicecandidate = function(ice){  //listen for candidate events
        if(!ice || !ice.candidate || !ice.candidate.candidate)  return;
        var myIP = /([0-9]{1,3}(\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/.exec(ice.candidate.candidate)[1];
        var pc2 = new MTgetByURI(myIP);
        setTimeout(function(){sendTVList();},3000);
        pc.onicecandidate = noop;
    };

There is no IP address in ice.candidate.candidate and therefore no match from RegExp.exec(). The strings I have encountered in ice.candidate.candidate are:

Chrome 108.0.5359.124 (64-bit) on Linux: 
"candidate:3568087678 1 udp 2113937151 ef312aaf-9672-41cf-9e82-df01ea85b8e2.local 54875 typ host generation 0 ufrag nJF2 network-cost 999"

I’ve replaced the myIP variable with my IP, and nothing. I don’t know where even start to debug this thing.
Do you have any new information?.
