Cannot import message files as `?raw` or `?url` in Vite

[jpritzkau-eepos]

Reporting a bug?

For use in a translation tool, I need to import the message files as strings without preprocessing, however this plugin tries to interpret the generated export default ... statement as JSON/YAML/etc.

Expected behavior

As the Vite docs would suggest, it should just import the file contents as a string without any errors.

Reproduction

const messages: Record<string, string> = import.meta.glob("./*.yaml", {
  eager: true,
  base: "./locales",
  query: "?raw",
  import: "default",
});

// https://vite.dev/config/
export default defineConfig({
  plugins: [vue(), vueDevTools(), vueI18n({ include: "src/locales/**" }), tailwindcss()],
  resolve: {
    alias: {
      "@": fileURLToPath(new URL("./src", import.meta.url)),
    },
  },
});

The resulting error:

This seems to be a regression introduced after @intlify/unplugin-vue-i18n 6.0.8.
