我想声明动作的有效载荷但它失败了

Question

我在 action redux slice reducer 中添加 payload 时遇到了问题，我在互联网上进行了搜索，但我没有找到解决这个问题的解决方案，所以我的代码 reducer：

topicsSlice code:
import {createSlice} from "@reduxjs/toolkit";

const topicsSlice = createSlice({
    name : "topics",
    initialState: {
       topics:{}
    },
    reducers: {
        addTopic: (state, action={type: "topics/addTopic",payload: {id, name, icon}}) => {
      
       const newTopic = {id: id, name: name, icon: icon}
       state.topics = {...state.topics, id: newTopic};
        }
    }

});

export const selectedTopics = (state) => state.topics.topics;
export const {addTopic} = topicsSlice.actions;
export default topicsSlice.reducer;

这里的解构就像

addTopic: (state, {payload: {id, name, icon}}) => {

我想声明动作的有效载荷但它失败了

i want to declare payload of action but it's failed
