websocket在RTCSessionDescription报价上自动断开连接

I am sending WebRTC - RTCSessionDescription offer packet to other connected "webrtc" PEER in a socket and as soon as I send RTCSessionDescription offer packet, my WebSocket sends me a signal, I am disconnected and the "RTCSessionDescripotion offer packet" never reaches to other peers.

I am using https://github.com/kataras/iris as go framework.

Here is my WebSocket configuration:

ws := websocket.New(websocket.Config{
    ReadBufferSize:  10240,
    WriteBufferSize: 10240,
})

ws.OnConnection(func(c websocket.Connection) {
    c.On("message", func(message string) {
    var dataIs map[string]string
    byteMsg := []byte(message)
    _ = json.Unmarshal(byteMsg, &dataIs)
        c.To(dataIs["room"]).Emit("message", dataIs["message"])
    })
    c.OnDisconnect(func() {
    c.EmitMessage([]byte("Connection Closed!"))
    fmt.Println("Closing Connection")
    ws.Disconnect(c.ID())
    })
})

And it prints on loop "Closing Connection" message.

I am expecting to see the "message event" being fired back to both peers, but it closes the connection and runs "closing connection" message on a continuous loop.
