section 46 퀴즈 관련 질문입니다

퀴즈를 해결하려고 해당 코드를 작성했는데 로그인을 하려고 하면 Context creation failed: 토큰 만료라는 400 오류가 뜹니다. (새로 가입해서도 해봤는데 똑같은 오류가 떴습니다.)

또한 useAuth를 사용했는데도 로그인 없이 성공페이지로 바로 접속됩니다. 뭐가 문제일까요?

useAuth

export const useAuth = ():void => {
  const router = useRouter()
  useEffect(()=>{
    if(localStorage.getItem("accessToken")===null){
      alert("로그인 ㄱ")
      void router.push("/z_quiz/section46/02")
    }},[])
}

완료 코드

import { gql, useQuery } from "@apollo/client"
import type { IQuery } from "../../../../src/commons/types/generated/types"
import { useAuth } from "../../../../src/components/commons/hooks/useAuth"
const FETCH_USER_LOGGED_IN = gql`
  query {
    fetchUserLoggedIn {
      email
      name
    }
  }
`
export default function LoginSuccessPage():JSX.Element {
  const { data } = useQuery<Pick<IQuery,"fetchUserLoggedIn">>(FETCH_USER_LOGGED_IN)
  useAuth()
  return <>{data?.fetchUserLoggedIn.name}님 환영합니다.</>
}
