Experimental appDir: true

    Why This Error Occurred

    Your project contains a directory named app/. Since Next.js 13, this is a reserved name.

    Possible Ways to Fix It

    To use the new app directory and its features, please add appDir: true to your configuration in next.config.js under experimental.

    /** @type {import('next').NextConfig} */
    const nextConfig = {
      experimental: {
        appDir: true,
    module.exports = nextConfig

    If you do not want to use the new app/ directory features yet, but have a directory named app/, rename the directory to something else.
