Regression 3.0.10 → 3.1.1: snowpack build

[aral]

When running npx snowpack build with the following config file:

module.exports = {
  mount: {
    '.snowpack': '/'
  },
  exclude: ['**/node_modules/**/*', '.git/**', 'build.js'],
  plugins: [
    ['@snowpack/plugin-svelte'],
  ],
  packageOptions: {
    polyfillNode: true
  },
  devOptions: {
    output: 'stream', // Don’t clear terminal.
    open: 'none',
    secure: true,
    port: 444,
  },
  buildOptions: {
    out: '.generated'
  },
  optimize: {
    bundle: true,
    minify: true,
    target: 'es2020',
  },
}

In 3.0.10

Works.

In 3.1.1

Throws the following error:

[optimize] No HTML entrypoints detected. Set "entrypoints" manually if your site HTML is generated outside of Snowpack (SSR, Rails, PHP, etc.).
[14:34:50] [snowpack] Error: [optimize] No HTML entrypoints detected. Set "entrypoints" manually if your site HTML is generated outside of Snowpack (SSR, Rails, PHP, etc.).

If I specify .snowpack/index.html as an entrypoint in optimize.entrypoints, e.g.,

  optimize: {
    // …
    entrypoints: ['.snowpack/index.html'],
 }

I get the following error instead:
