Astro fails to build with prefixDefaultLocale: true,

[Cacamoto]

Astro Info

Node                     v21.3.0
System                   macOS (arm64)
Package Manager          npm
Output                   hybrid
Adapter                  @astrojs/node
Integrations             @astrojs/tailwind

If this issue only occurs in one browser, which browser is a problem?

No response

Describe the Bug

If I set prefixDefaultLocale: false, astro build works just fine. If I chage it to true, it fails with this CLI message:

 prerendering static routes 
Cannot find module .../dist/server/src/pages/index.astro' imported from .../node_modules/astro/dist/core/build/generate.js

And I'm not missing the /pages/index.astro

My astro.config.mjs:

import { defineConfig } from "astro/config";
import tailwind from "@astrojs/tailwind";
import solidJs from "@astrojs/solid-js";
import node from "@astrojs/node";

// https://astro.build/config
export default defineConfig({
  integrations: [tailwind(), solidJs()],
  output: "hybrid",
  i18n: {
    defaultLocale: "en_",
    locales: ["en_", "lt_"],
    routing: {
      prefixDefaultLocale: true,
    },
  },
  adapter: node({
    mode: "standalone",
  }),
});

What's the expected result?

Succesful build
