Details of thrown WebSocketException unavailable

[fulstadev]

I'm trying to establish a websocket connection, through the following code:

final WebSocketChannel channel = WebSocketChannel.connect(
          Uri.parse(
              'wss://ws.mywsexample.com/?user=${user}&auth=${auth}'),
        );

        print('connecting...');

        /// Await completion of the connection attempt
        try {
          await channel.ready;
        } on SocketException catch (e) {
          print(e.message);
        } on WebSocketChannelException catch (e) {
          print(StackTrace.current.toString());
          print(e.inner!.toString());
          print(e.message);
        } catch (e) {
          print(e.toString);
        }

Whenever I run this code in an iOS simulator, I get that the second catch clause (WebSocketChannelException) is entered. But the problem is that I am unable to get any details / insight about the thrown error, e.g.:

• print(e.message) simply gives Instance of 'WebSocketException'
• print(e.inner.toString()) gives the same
• The stack trace delivers the same, simply with the additional info of my function running the code above

This is not very helpful for debugging; how can I check the actual details of the thrown Exception? I can't even find any WebSocketException class in the package source?

I'm also getting same error, I have followed the code from web-socket-cookbook-example.
also added for better error fetching:

    try {
      final channel = WebSocketChannel.connect(
        Uri.parse('ws://nixbin:3000'),
      );

      channel.stream.listen(
        (message) => print('Received: $message'),
        onError: (error) => print('Error: $error'),
        onDone: () => print('Done'),
      );
    } catch (e) {
      print('Connection error: $e');
    }

nixbin is host only accessible within my devices.
getting error

Is there anything missing? is it a bug for self-hosted websockets.
