안녕하세요 제로초님,
useEffect(() => {
console.log('DMList: workspace 바꼈다', workspace);
setOnlineList([]);
}, [workspace]);
useEffect(() => {
socket?.on('onlineList', (data: number[]) => {
console.log("data", data)
setOnlineList(data);
});
// socket?.on('dm', onMessage);
// console.log('socket on dm', socket?.hasListeners('dm'), socket);
return () => {
// socket?.off('dm', onMessage);
// console.log('socket off dm', socket?.hasListeners('dm'));
// socket?.off('onlineList');
};
}, [socket]);여기까지 진행하고 슬랙앱을 봤을 때, (나) 여기에만 초록불이 잘 들어오는걸 확인했는데, 여기서 다른 탭을 갔다오거나 새로고침을 하면 제 생각엔 swr이 작동을 안하는 것 같습니다. userdata를 못받아와서 갑자기 loginpage로 튕겨져 나가는데, 쿠키는 남아있는데 계속 로딩중이라고 뜹니다. 백이랑 프론트 서버를 재시작하면 다시 되긴하는데, 채널을 옮기거나 하면 다시 오류가 시작되는데 이유를 못찾겠습니다.
프론트 쪽
백쪽
어디서 꼬인건지 잘 모르겠습니다. mutate쪽이 문제인가 싶어서 지워봤는데 똑같습니다..

프론트에서 socket.emit('login') 부분 코드 보여주세요. 거기서 channels가 백엔드로 전달되지 않았습니다.
