使用Redux Toolkit configureStore遇TypeScript类型不匹配错误求助

刚结束培训，正在独自完成第一个项目，未借助培训资料。此前学习的是createStore方法，现在按Redux推荐改用configureStore，但遇到了无法解决的类型错误。

错误提示：Type '{ id: string; name: string; price: number; amount: number; }' is not assignable to type 'ShoppingState'

相关代码 #

Store配置代码 #

import { configureStore } from '@reduxjs/toolkit';
import { CartProductsSliceState } from '../interfaces/slices/cartProductsSlice.interface';
import { cartProductsSlice } from './cartRedux';

export const initialState: CartProductsSliceState =
  {
    cartProducts: [
      {
        id: '1',
        name: 'pizza',
        price: 12,
        amount: 1,
      },
    ],
  };

const store = configureStore({
  reducer: {
    cartProducts: cartProductsSlice.reducer,
  },
});

export default store;

接口定义 #

CartProductsSliceState 接口

import { ShoppingState } from '../../redux/mainTypes';

export interface CartProductsSliceState {
  cartProducts: ShoppingState[];
}

cartProduct 接口

export interface cartProduct {
  id: string;
  name: string;
  price: number;
  amount: number;
}

ShoppingState 接口（CartState 即 cartProduct 接口）

export interface ShoppingState {
  cartProducts: CartState;
}

不清楚错误原因，希望获得帮助。
