server 쪽에서 should be a number of seconds or string representing a timespan 에러가 발생합니다

Window, node 22 버전 사용중입니다. 4-5 로그인 연동하기에서 회원가입까진 연동이 되는데 로그인 api 요청시 500에러가 발생합니다.

postLogin 에서 엔드포인트만 /auth/signup로 바꾸면 회원가입은 정상적으로 요청이 됩니다.

   const token = jwt.sign({ userId }, secret, {
     expiresIn: '1h', // 1 hour
   });
