Nx: @nrwl/next does not pickup new v10 Internationalized Routing (i18n object in next.config.js)

[pmualaba]

Current Behavior

@nrwl/next does not pickup new v10 Internationalized Routing (i18n object in next.config.js)

Expected Behavior

Vercel added Internationalized Routing (i18n object in next.config.js) in Next v10.
When I add an i18n configuration object in next.config.js I excpect that the Next app in Nx is picking it up and activates v10 Internationalized Routing.

Steps to Reproduce

1. In an empty Nx workspace create a Next app :

nx g @nrwl/next:app web

1. in /apps/web/next.config.js add the i18n configuration object as per the official docs

 module.exports = {
  i18n: {
    locales: ['en', 'fr', 'nl'],
    defaultLocale: 'en',
  },
};

1. launch the Next app and try to navigate to /nl or /fr : This should display the Index Page, but it renders 404 instead.

nx serve web

@pmualaba For what I can see @nrwl/next use "next": "^9.3.3". Since i18n is a v10 feature I think is expected to not work. I would not tag as a bug.

If you add next v10 in your project i18n will work works (for what I've seen with a quick test).

I also have a problem with Internationalized Routing.

If I run a build though NX as: ./node_modules/.bin/nx serve app --prod
"/" route without a locale prefix (next uses default locale in this case) works correctly

If I go to dist folder, install dependencies and run through NPM as: npm start
"/" route without a locale prefix returns 404

Seems like next.config.js is not copied on build to dist folder

Seems like next.config.js is not copied on build to dist folder

If I copy next.config.js to dist folder, routing works correctly.
