I Am Getting This Error Functions are not valid as a React child. This may happen if you return a Component instead of from render. Or maybe you meant to call this function rather than return it

And

Matched leaf route at location "/" does not have an element. This means it will render an with a null value by default resulting in an "empty" page.

This One

App.js file is

import React, { Component } from 'react'; 
import HomePage from './pages/HomePage'; 
import { BrowserRouter, Routes, Route, } from 'react-router-dom'; 
import './App.css'; 
import { render } from '@testing-library/react';

class App extends Component {   render() {
    return (
      <BrowserRouter>
      <Routes>
          <Route path='/' element={HomePage} exact/>
      </Routes>
      </BrowserRouter>
    );   } }

export default App;

And Homepage.js

import React from 'react';

const HomePage = () => (
    <>
    <h1>Hello, welcome to my blog!</h1>
    <p>

CodePudding user response：

Replace <Route path='/' element={HomePage} exact/> with <Route path='/' element={<HomePage/>} exact/>.

You need to pass it as an element and not as a prop since react router v6.
