When using next/bundle-analyzer on the latest NextJS version with turbopack, when I run:
npm run dev

I get the following in my console:

⚠ Webpack is configured while Turbopack is not, which may cause problems.
 ⚠ See instructions if you need to configure Turbopack:
  https://nextjs.org/docs/app/api-reference/next-config-js/turbo

Next config:

import type { NextConfig } from "next";
import withBundleAnalyzer from "@next/bundle-analyzer";

const isAnalyze = process.env.ANALYZE === "true";

const nextConfig: NextConfig = {
  reactStrictMode: true,
};

export default withBundleAnalyzer({ enabled: isAnalyze })(nextConfig);
