Tried emitting when not connected socket io objective-c

I tred to use socket io library but i've problem to emit :
this is js code :

var io = require('socket.io')();

io.on('connection', function(socket) {
  console.log('connected!');
  console.log('roomId request: ' + socket.handshake.query.roomId);
  let roomId = socket.handshake.query.roomId;


  socket.on(roomId, function(data) {

    console.log('----------------------------------------------');
    console.log("data: " + JSON.stringify(data));

   socket.emit(roomId,data);
    console.log('----------------------------------------------');
  });

});

io.listen(8080);

and this from code objective-c:-

  NSURL* url = [[NSURL alloc] initWithString:@"http://localhost:8080"];
    SocketManager* manager = [[SocketManager alloc] initWithSocketURL:url config:@{@"log" : @YES,@"connectParams":@{@"roomId": self.requestId}}];
    socket = manager.defaultSocket;
   

    
    [socket on:@"roomId" callback:^(NSArray* data, SocketAckEmitter* ack) {
        
      //
        
    }];
    [socket connect];

and always got this error : - LOG SocketIOClient{/}: Handling event: error with data: ["Tried emitting roomId when not connected"]

please help

Wait till you get the "connect" event before emitting anything.
