Webpack workbox Can't find self.__WB_MANIFEST in your SW source

问题

I migrate from v4 to v5 of webpack-workbox-plugin but when I try to build, I got error:

ERROR in Can't find self.__WB_MANIFEST in your SW source.
Child InjectManifest:
    Asset     Size  Chunks             Chunk Names
    sw.js  1.5 KiB       0  [emitted]  InjectManifest
Child html-webpack-plugin for "index.html":
     1 asset

Do __WB_MANIFEST will create in a precach-manifest file and import automatically like v4?

WebpackConfig :

new WorkboxPlugin.InjectManifest({
      swSrc: 'sw.js',
      chunks: ['*.chunk.js'],
      exclude: [/\.(?:png|jpg|jpeg|svg)$/, /\.map$/, /manifest\.json$/, /service-worker\.js$/, /sw\.js$/],
      include: [path.resolve(process.cwd(), 'build')],
    }),

My sw.js:

importScripts('./ChabokSDKWorker.js', 'https://storage.googleapis.com/workbox-cdn/releases/5.0.0/workbox-sw.js');

/* eslint-disable no-undef */

if (workbox) {
  workbox.core.skipWaiting();
  workbox.core.clientsClaim();
  workbox.precaching.cleanupOutdatedCaches();

  // eslint-disable-next-line no-restricted-globals,no-underscore-dangle
  workbox.precaching.precacheAndRoute(self.__WB_MANIFEST);

  // java-script files cache
  workbox.routing.registerRoute(
    new RegExp('.+\\.js$'),
    workbox.strategies.StaleWhileRevalidate({

      plugins: [
        new workbox.expiration.Plugin({
          maxEntries: 20,
          maxAgeSeconds: 60 * 60 * 24 * 7,
          purgeOnQuotaError: true,
        }),
        new workbox.cacheableResponse.Plugin({
          statuses: [0, 200],
        }),
      ],
    }),
  );

  // css files cache
  workbox.routing.registerRoute(

    workbox.strategies.StaleWhileRevalidate({

      plugins: [
        new workbox.expiration.Plugin({
          maxEntries: 5,
          maxAgeSeconds: 60 * 60 * 24 * 7,
          purgeOnQuotaError: true,
        }),
        new workbox.cacheableResponse.Plugin({
          statuses: [0, 200],
        }),
      ],
    }),
  );

  // image files cache
  workbox.routing.registerRoute(
    new RegExp('.+\\.(png|jpg|jpeg|svg)$'),

      plugins: [

        new workbox.cacheableResponse.Plugin({
          statuses: [0, 200],
        }),
      ],
    }),
  );

  workbox.routing.registerRoute(
    new RegExp('/.*'),
    workbox.strategies.NetworkFirst({}),
    'GET',
  );
} else {
  console.log(`Boo! Workbox didn't load 😬`);
}

It was my webpack config for injectManifest bug, I fixed it like this :

    new WorkboxPlugin.InjectManifest({
      swSrc: path.join(process.cwd(), '/app/resources/service-worker.js'),
      swDest: 'sw.js',
      exclude: [
        /\.map$/,
        /manifest$/,
        /\.htaccess$/,
        /service-worker\.js$/,
        /sw\.js$/,
      ],
    }),

and now self.__WB_MANIFEST will replace with list of precache files
