Javascript 侦听器参数必须是使用套接字io的函数错误类型

使用下面的函数使用套接字io加入连接，以使工作区出错

“listener”参数必须是Function类型

如何解决这个错误，下面我已经粘贴了整个错误，我对socketio还不熟悉，按照

io.on（）

函数的预期，什么是满足需求的最佳方法

export const roomJoin = (socket, io, msg) => {
        if (msg.room_id) {
            socket.join(msg.room_id, () => {
            io.on('room_join', function(socket){
                socket.emit('request',{ status: true, msg: "room join", room_id: msg.room_id });
                return
              });
            })

        } else {
            socket.emit('room_join', { status: false, message: "Invalid/Missing data" });
        }
    }
