伙计们，我在调试最近在我的应用程序中遇到的错误时遇到了麻烦，即“createStore 的 preloadedState 参数具有意外类型的 Null.Expected 参数是具有填充键的对象：“登录””

import {
  AUTH_USER,

  AUTH_ERROR
} from './login.types';

const INITIAL_STATE = { errors: null, authenticated: false, admin_privileges: false };

export const login =  (state = INITIAL_STATE, action) => {
 switch(action.type) {
     case AUTH_USER:
            return { ...state, errors: null, authenticated: true };
        case SET_ADMIN_PRIVILEGES:
