Client/Chat.Js UseEffect(() => { const { name, room

Question

Client/Chat.Js UseEffect(() => { const { name, room

} = queryString.parse(location.search);
socket = io(endpoint);
socket.emit("join", { name, room });
setName(name);
setRoom(room);

return () => {
socket.emit("disconnect");
socket.disconnect();
};
}, [location.search]);

server/index.js
io.on("connection", socket => {
socket.on("join", ({ name, room }, cb) => {
const { user, error } = addUser({
id: socket.id,
name,
room
});
socket.join(user.room);
});
подскажите,пожалуйста, почему Cannot read property 'room' of undefined при релоаде страницы?
