ERROR: FormatException: ERROR: Failed to parse device description. XmlParserException: Expected a single root element at 1:10 - http://192.168.31.237:9080

Example code that I used

import 'package:upnp2/upnp.dart';

// NOTE: Open the example directory to see more elaborate examples
main() async {
  final disc = DeviceDiscoverer();
  await disc.start(ipv6: false);
  disc.quickDiscoverClients().listen((client) async {
    try {
      final dev = await client.getDevice();
      print('Found device: ${dev!.friendlyName}: ${dev.url}');
    } catch (e, stack) {
      print('ERROR: $e - ${client.location}');
      print(stack);
    }
  });
}

Debugged the response in discovery.dart file line 372 and the value of the content variable is status=ok

It seems, that the XML send back from the device has some formatting errors, could you maybe provide the output http://192.168.31.237:9080 ? Or debug the issue and look what the response returned from the device is?

[guyluz11]

The response from the device is status=ok

[daniel-naegele]

I need the body (see Response tab when inspecting a request) of the message, maybe you could paste it here

[guyluz11]

We'll test it again at the end of the week when I will get back to the same WiFi

[guyluz11]

Ha ha,
as expected it is the same

[daniel-naegele]

What kind of device is this? This does not seem to be in accordance with the UPnP specification

Smart TV made by LG.
it is like android tv but is not android at all, and operating system called webos
