當我使用我的反應應用程序設置反應警報時出現錯誤未捕獲錯誤：對象作為 React 子項無效

Question

我收到了這個錯誤：

react-dom.development.js:14748 Uncaught Error: Objects are not valid as a React child (found: object with keys {$$typeof, render}). If you meant to render a collection of children, use an array instead.
    in Unknown (created by App)
    in Provider (created by App)
    in div (created by App)
    in App
    in Provider
    at throwOnInvalidObjectType 

這是我的警報組件

import React, { Component , Fragment} from 'react'
import { withAlert } from "react-alert";
export class Alerts extends Component {

        componentDidMount(){
            this.props.alert.show("it worked");
        }


    render() {
        return (
            <Fragment>

            </Fragment>
        );
    }
}

export default withAlert(Alerts);

這是我的 App.js

import React ,{ Component, Fragment }  from "react";
import { render } from "react-dom";
import {Provider as AlertProvider} from 'react-alert';
import AlertTemplate from 'react-alert-template-basic';
import Header from './components/Header';
import Leads from './components/leads';
import AddLead from './components/AddLead';
import  Alerts from './components/Alerts'
import { Provider } from 'react-redux';
import store from './store';
import { connect } from 'react-redux';


const alertOptions = {
    timeout:3000,
    position:"top center"
}

class App extends Component{
    render(){
        return(
            <div>
                <AlertProvider template={AlertTemplate} {...alertOptions}>
                <Fragment>
                    <Header/>
                    <Alerts/>
                    <Leads/>
                    <AddLead/>
                </Fragment>
                </AlertProvider>
            </div>

        )
    }
}

export default App;
render(<Provider store={store}><App/></Provider>, document.getElementById("app"));

我的錯誤減少器：

import { GET_ERRORS } from '../actions/Types';


const initialState = {
    msg: {},
    status:null
}

export default function (state = initialState, action) {
    switch(action.type){
        case GET_ERRORS:
            return {
                msg:action.payload.msg,
                status:action.payload.status
            };
        default:
            return state;
    }
}

Answer 1

將 Alert 組件的最后一行從export default withAlert(Alerts); export default withAlert()(Alerts); 根據反應警報文檔。
