为什么我在离线时看到 start_url 没有响应 200？

如何解决为什么我在离线时看到 start_url 没有响应 200？

我使用 Create React App、Next.js 和 next-pwa (https://www.npmjs.com/package/next-pwa)

我设置我的 next.config.js :

const withPWA = require('next-pwa')
const prod = process.env.NODE_ENV === 'production';

module.exports = withPWA({

  pwa: {
    dest: 'public',disable: prod ? false : true,},async redirects() {
    return [
      {
        source: '/franchise',destination: '/franchise/franchising',permanent: false,{
        source: '/musteri-hizmetleri',destination: '/musteri-hizmetleri/kisisel-verilerin-korunmasi',]
  },})

我的public\manifest.json：

{
  "short_name": "Little","name": "Little","icons": [
    {
      "src": "favicon.png","sizes": "64x64 32x32 24x24 16x16","type": "image/x-icon","purpose": "maskable"
    },{
      "src": "favicon-512.png","type": "image/png","sizes": "512x512"
    }
  ],"start_url": ".","display": "standalone","theme_color": "#000000","background_color": "#ffffff"
}

但是当我开始下次开始 Lighthouse 向我展示这个

我该如何解决这个问题：离线时 start_url 没有响应 200??
