Unable to connect using JWT

[asafgo]

Hi,

My Server side code is SignalR and I am unable to connect to it if I am using JWT. if I am not using JWT at server side, I am able to connect.

I am able to connect without any problem with same approach as my following Flutter code when using Postman and C# client code using web sockets.

My Flutter code:

final String token = '<The JWT Token>';
final String wsUrl ='wss://<Web Site URL>/progresshub?access_token==$token';
final wsURI = Uri.parse(wsUrl);
final channel = WebSocketChannel.connect(wsURI);

Also the following code does not return any error and channel object is empty:

try {
      await channel.ready;
    } on SocketException catch (e) {
      debugPrint('ERROR: - SocketException - ${e.message}');
      //print(e.message);
    } on WebSocketChannelException catch (e) {
      debugPrint('ERROR: - SocketException - ${e.message}');
    }

For some reason I am able to add sink's like so:

 channel.sink.add('{"protocol":"json","version":1}');

    channel.sink
        .add('{"type":1,"target":"AssociateJob","arguments":["$jobID"]}');

Error will raise without any location where it is when trying to listen:

channel.stream.listen(
      (message) {

But onError: (error) => debugPrint('Error: ' + error) is not triggered.

Thanks for any help, AG
