我不明白为什么我得到未定义的错误，有人可以帮助我解决为什么我无法访问身份验证状态？
src/queries/authSlice.jsx：

import { createSlice } from "@reduxjs/toolkit";

const initialState = {
    isAuthenticated: false,
}

const authSlice = createSlice({
    name: 'auth',
    initialState,
    reducers: {
        loginSuccess: (state) => {
            state.isAuthenticated = true;
        },
        logoutSuccess: (state) => {
            state.isAuthenticated = false;
        }
    }
});

export const selectUser = (state) => console.log(state.auth)
export const { loginSuccess, logoutSuccess } = authSlice.actions;
export default authSlice.reducer;

字符串
我得到错误Auth State: undefined
src/queries/rootReducer.jsx：

import { combineReducers } from 'redux';
import authReducer from './authSlice';
import { queriesApi } from './queries';

const rootReducer = combineReducers({
    auth: authReducer,
    [queriesApi.reducerPath]: queriesApi.reducer
});

export default rootReducer;

src/queries/store.jsx：

import { configureStore } from '@reduxjs/toolkit';
import { queriesApi } from './queries';

const store = configureStore({
    reducer: {
        [queriesApi.reducerPath]: queriesApi.reducer
    },
    middleware: (getDefaultMiddleware) => {
        return getDefaultMiddleware().concat(queriesApi.middleware)
    }
});

export default store;

SignIn.jsx代码：

import * as React from 'react';
import { ThemeProvider } from '@mui/material/styles';
import { useDispatch, useSelector } from 'react-redux';
import { loginSuccess, logoutSuccess, selectUser } from '../queries/authSlice';

const defaultTheme = createTheme();

export default function SignIn() {
const data = new FormData(event.currentTarget);
    console.log({
      email: data.get('email'),
      password: data.get('password'),
    });
  };

  const dispatch = useDispatch();
  const authState = useSelector(selectUser);
  console.log('Auth State:', authState);

  const isAuthenticated = authState.isAuthenticated;

  const handleLogin = () => {
    dispatch(loginSuccess());
  };

  const handleLogout = () => {
    dispatch(logoutSuccess());
  };

  return (
    <ThemeProvider theme={defaultTheme}>
      <div>
      {isAuthenticated ? (
        <button onClick={handleLogout}>Logout</button>
      ) : (
        <button onClick={handleLogin}>Login</button>
      )}
    </div>
    </ThemeProvider>
  );
}

**更新：我已经添加了登录页面，其中Auth State：undefined正在控制台中生成，但问题是：

我不明白为什么在这一行导出const selectUser =（state）=> console.log（state.auth）state.auth会生成未定义的输出？
