Hi, I have a problem using RR v7, framework mode with ssr: false with internalization library react-i18next.
Locally, when I'm running npm run dev, build, I have no Issues, the application runs without any problems.
If I try to deploy it, I have this error:

✗ Build failed in 193ms
[react-router] Cannot access 'i18n' before initialization

}

I have imported i18next instant to root.tsx

import './i18next.ts'
My configuration file is almost identical to this docs file example

react-router.config.ts

import type { Config } from '@react-router/dev/config';

export default {
  // Server-side render by default, to enable SPA mode set this to `false`
  ssr: false,
} satisfies Config;

vite.config.ts

import { reactRouter } from '@react-router/dev/vite';
import tailwindcss from '@tailwindcss/vite';
import { defineConfig } from 'vite';
import tsconfigPaths from 'vite-tsconfig-paths';

export default defineConfig({
  plugins: [tailwindcss(), reactRouter(), tsconfigPaths()],
  server: {
    port: 5174,
  },
});

root.tsx

import {
  isRouteErrorResponse,
  Links,
  Meta,
  Outlet,
  Scripts,
  ScrollRestoration,
} from 'react-router';

import type { Route } from './+types/root';
import './app.css';
import './i18next';

export const links: Route.LinksFunction = () => [
  { rel: 'preconnect', href: 'https://fonts.googleapis.com' },
  {
    rel: 'preconnect',
    href: 'https://fonts.gstatic.com',
    crossOrigin: 'anonymous',
  },
  {
    rel: 'stylesheet',
    href: 'https://fonts.googleapis.com/css2?family=Inter:ital,opsz,wght@0,14..32,100..900;1,14..32,100..900&display=swap',
  },
];

export function Layout({ children }: Readonly<{ children: React.ReactNode }>) {
  return (
    <html lang="en">
      <head>
        <meta charSet="utf-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1" />
        <Meta />
        <Links />
      </head>
      <body>
        {children}
        <ScrollRestoration />
        <Scripts />
      </body>
    </html>
  );
}

export function HydrateFallback() {
  return <p>Loading ...</p>;
}

export default function App() {
  return <Outlet />;
}

export function ErrorBoundary({ error }: Readonly<Route.ErrorBoundaryProps>) {
  let message = 'Oops!';
  let details = 'An unexpected error occurred.';
  let stack: string | undefined;

  if (isRouteErrorResponse(error)) {
    message = error.status === 404 ? '404' : 'Error';
    details =
      error.status === 404
        ? 'The requested page could not be found.'
        : error.statusText || details;
  } else if (import.meta.env.DEV && error && error instanceof Error) {
    details = error.message;
    stack = error.stack;
  }

  return (
    <main className="pt-16 p-4 container mx-auto">
      <h1>{message}</h1>
      <p>{details}</p>
      {stack && (
        <pre className="w-full p-4 overflow-x-auto">
          <code>{stack}</code>
        </pre>
      )}
    </main>
  );
}
