Angular NGRX选择器无法读取属性'；旅游供应商'；未定义的

我已经在angular应用程序中实现了ngrx。我的管理模块我有一个API调用，用于从服务器获取一些数据，我创建了

effect

，并成功执行了它。我可以在redux开发工具中看到这一点。使用选择器选择数据时出现问题。在浏览器控制台中，出现此错误

错误类型错误：无法读取未定义的属性“tourProvider”

。 我使用的是angular 8和ngrx 8.0.1

这是我的应用程序级别状态root-state.ts

import { CustomerStateKey, CustomerState } from "../customer/customer- 
store/customer.state";
import { AdminStateKey, AdminState } from "../admin/admin- 
store/admin.state";
export interface State {
   [CustomerStateKey]: CustomerState;
   [AdminStateKey]: AdminState;
 }

模块级状态admin.state.ts

import { TourproviderState } from "./state/tourprovider.state";
import { createFeatureSelector } from "@ngrx/store";
import { State } from "src/app/root-store/root-state";

export interface AdminState {
tourproviderState: TourproviderState;
}

export const AdminStateKey = 'admin';

export const SelectAdminState = createFeatureSelector<State, AdminState> 
(AdminStateKey);

这是我的选择器文件tourproivder.selector.ts

import { createSelector } from '@ngrx/store';
import { SelectAdminState, AdminState } from '../admin.state';

export const selectTourprovider = createSelector(SelectAdminState, ({ 
tourproviderState }: AdminState) => tourproviderState.tourProvider);

export const selectIsTourproviderLoading = 
createSelector(SelectAdminState, 
({ tourproviderState }: AdminState) => tourproviderState.isLoading);

export const selectTourproviderError = createSelector(SelectAdminState, ({ 
tourproviderState }: AdminState) => tourproviderState.error);

数据模型类型tourprovider.model.ts

export interface Tourprovider {
    id: number,
    name: string,
    email: string,
    description: string,
    logo: string,
    contactNum: string,
    contactNum2: string,
    streetAddress: string,
    streetAddress2: string,
    zipCode: string,
    city: string,
    state: string,
    countryCode: string,
    countryName: string,
}

数据模型类型request-result.model.ts

export interface RequestResult<T> {
  code: number;
  message: string;
  payload: T;
}

导出接口请求结果{
代码：编号；
消息：字符串；
有效载荷：T；
}

你能在stackblitz上共享你的代码吗？嘿，我知道了。问题是我在管理状态和选择器中使用了不同的名称，或者你能在stackblitz上共享你的代码吗？嘿，我知道了。问题是我在管理状态和选择器中使用了不同的名称
