로그인 버튼 클릭 시 아래 오류가 뜨는데 어디가 문제일까요.?
index.js:43 은 입니다.

const rootReducer = (state = initialState, action) => {
  switch (action.type) {
    case HYDRATE:
      console.log("HYDRATE", action);
      return { ...state, ...action.payload };
    case LOG_IN:
      return {
        ...state,
        user: {
          user: dummyUser,
          isLoggedIn: true,
          loginData: action.data,
          // user: action.data,
        },
      };
    case LOG_OUT:
      return {
        ...state,
        user: {
          ...state.user,
          isLoggedIn: false,
          user: null,
        },
      };
    default:
      return state;
  }

선생님 해결했습니다.. 액션을 가져올 때 { } 없이 그냥 가져와서 오류가 난 것 같아요.
import { loginAction } from "../reducers/index";
