hi, please can you include your server and client configurations?.

[maulanazh15]

My server is using laravel with pusher broadcast driver and laravel-websockets as the websockets, here is my configurations for pusher in laravel .env :

This is my configurations for pusher client in my flutter app :

Btw, this error cause my app to stop working like this picture below when i try subscribing to a private channel:

Although in my laravel websockets dashboard, it successfully subscribe to a private channel :

Yeah that's all the information i can get

Thank you for your respond to this error

[AbdoPrDZ]

As I see everything looks good Have you tried to cleaning your project before? 1- flutter clean 2- Make sure to delete the “build” folder. 3- Delete the application from the emulator. 4- Run the application

[maulanazh15]

I have tried your method. It's still showing the same error after I do the flutter clean, delete the app in emulator, and rerun the application.

[AbdoPrDZ]

i found your project in your profile i tested it, i faced the same error I searched for the root of the problem but did not find it I tried to separate the command of listening to the event from the command of subscribe to the channel, and the method worked But I did not find what is the root problem Note: some times your method is working

i think the safe way is put the listen command after subscribing in onSubscribeSuccess event

final channel = LaravelEcho.instance.private('channelName');
channel.onSubscribedSuccess(() {
  channel.listen('eventName', (event) {
    print(
      'event[${event.runtimeType}]: $event', // event[String]: {"key": "value"}
    );
    print(
      'decodedData: ${jsonDecode(event)}', // decodedData: {"key": "value"}
    );
  });
});

Note: event is not a class, is a sended data (String)

[AbdoPrDZ]

• There was a problem with onSubscribeSuccess event, i fix it in new version of laravel_echo_null^0.0.5+6
• i see you have commented script, you used laravel_echo with "socket.io", there is any problem with it?

[maulanazh15]

Thank you very much for your response, i didn't expect you also try my project to fix this error. I have tried your method, i change the library from laravel_echo to laravel_echo_null 0.0.5+7 from you, and then write the code for subscribing private channel just like your code, but somehow it's still showing the same error. This is my function to create laravel echo :

Echo<PUSHER.PusherClient, PusherChannel> createLaravelEcho(String token) {
  Echo<PUSHER.PusherClient, PusherChannel> echo = Echo.pusher(
    PusherConfig.key,
    authEndPoint: PusherConfig.hostAuthEndPoint, // String?: auth host
    authHeaders: {
      // authenticate headers
      'Authorization': 'Bearer $token',
      'Content-Type': 'application/json',
      'Accept': 'application/json',
    },
    // cluster: PusherConfig.cluster, // String?: pusher cluster
    host: '10.0.2.2',
    wsPort: 6001,
    encrypted: false,
    activityTimeout: 120000,
    pongTimeout: 30000,
    maxReconnectionAttempts: 6,
    maxReconnectGapInSeconds: 30,
    enableLogging: true,
    autoConnect: true, // bool: client connection automatically
    nameSpace: 'nameSpace',
  );

  return echo;
}

I change the autoConnect option to true, because the laravel_echo_null seems not auto connect itself. This is my code for subscribing to private channel :

void listenChatChannel(ChatEntity chat) {
    // print(LaravelEcho.socketId);

    final channel = LaravelEcho.instance.private('chat.${chat.id}');
    channel.onSubscribedSuccess(() {
      channel.listen('.message.sent', (event) {
        print(
          'event[${event.runtimeType}]: $event', // event[String]: {"key": "value"}
        );
        print(
          'decodedData: ${jsonDecode(event)}', // decodedData: {"key": "value"}
        );
      });
    });
  }

When i run the application, its still showing the same error. Although the onSubscribedSuccess is successfully running, the prove is on the debug console log :

The error shows after the onSubscribedSucces successfully running :

I also try to comment the channel.onSubscribedSuccess, just to confirm when the problem occured, is it after, before, or as the subcribing process run.

void listenChatChannel(ChatEntity chat) {
    // print(LaravelEcho.socketId);

    final channel = LaravelEcho.instance.private('chat.${chat.id}');
    // channel.onSubscribedSuccess(() {
    //   channel.listen('.message.sent', (event) {
    //     print(
    //       'event[${event.runtimeType}]: $event', // event[String]: {"key": "value"}
    //     );
    //     print(
    //       'decodedData: ${jsonDecode(event)}', // decodedData: {"key": "value"}
    //     );
    //   });
    // });
  }

And its still show the same error. My guess, the problem occurred after subscribing process is done, because in my laravel-websockets, its successfully subscribe to private channel just like this :

Does the Android version in the emulator also affect the errors? What Android version you are using for the emulator? My Android version for the emulator is Android 7.0.

Yeah, I also try the socket_io_client, laravel_echo_null, and fixed-laravel-echo-server, but the problem is, when subscribing to a private channel, the request for authorizing to private channel from socket_io_client, the socket_id is null. It seems, that the socket_io_client didn't include the socket_id in their request. Or is the problem in laravel-echo-null? This is my error log in fixed-laravel-echo-server :

I am using http subscriber in fixed-laravel-echo-server, and pusher as the broadcast driver in laravel. I have not try the redis subscriber in fixed-laravel-echo-server and redis as broadcast driver in laravel though, i don't know how it works. Maybe I will try that, if i am not finding the solution for the socket_id request in the http subscriber.

Thank you very much for your response to this issue. Sorry for the delayed comment from me.
