Emit doesn't work

[WGPavell]

I try to emit with this client but in most cases server doesn't receive it. Client logs:

I connect to server with following code:

self?.socketManager.setConfigs([.version(.two), .reconnects(true), .extraHeaders(["billing-token": token, "User-Agent": userAgent]), .forceNew(true), .compress, .forceWebsockets(true), .log(true)])
let socket = self?.socketManager.defaultSocket
socket?.on("connect", callback: { data, ack in
    print("connected")
    self?.socketManager.handleQueue.async {
        socket?.once(clientEvent: .pong, callback: { data, ack  in
            socket?.emit("personal_chat", "fdsfds") {
                print("emitted")
            }
        })
    }
})
socket?.on("personal_chat_send_message", callback: { data, ack in
    debugPrint(data)
})
socket?.connect()

In logs connected and emitted are printed. Early I try it without handleQueue, pong event, data (just only socket.emit with event name) and result was same. I try to add delay and emit fires more often but not always.

On server I have next code:

io.on('connection', (socket) => {
    let userData = socketsData.get(socket)
    console.log(`${socket.id} connected`);
    // ... other events
    socket.on("personal_chat", async () => {
        console.log(`subscribe to ${userData.chatId} chat`);
        socket.join(`personal_chat_${userData.chatId}`);
    });
    socket.on("disconnect", () => {
        console.log(`${socket.id} disconnected`);
        socketsData.delete(socket);
    });
});

Server logs:

As you can see, I tried to send emit several times, but nothing reaches the server. I tried to do it from the JS client and everything is emitted fine. What could be the problem and how can it be solved?
