错误图片

使用 React.js 编码时遇到错误。我对此没有任何想法。因此我不知道如何提出这个问题。此外，我附上了一个错误文件的图片。放上 App.js、Header.js 和 package.json 文件。我尝试解决这个问题一个小时了，但没有成功。请帮忙。

App.js

import { Fragment } from "react";
import Header from "./components/Layout/Header";

function App() {
  return (
    <Fragment>
      <Header/>
    </Fragment>
  );
}
export default App;

Header.js

import React, {Fragment} from 'react'
import mealsImage from '../../assets/meals.jpg'
import classes from './Header.module.css'

const Header = (props) => {
  return (
    <Fragment>
        <header className={classes.header}>
            <h1>ReactMeals</h1>
            <button>Cart</button>
        </header>
        <div className={classes=['main-image']}>
            <img src={mealsImage} alt='A Table full of delicious meals' />
        </div>
    </Fragment>
  )
}
export default Header
