Nextjs 14 pages folder, output:"export" is not working

I'm working on nextjs 14.2 version with pages folder. I don't have any images, /api routes or anything yet. This is an old nextjs app, updated to latest version.

When I run npm run build, it is not generating .out folder. Only .next folder is created.

nextjs.config.mts:

const nextConfig: NextConfig = {
  output: 'export',
  reactStrictMode: true,
  webpack(config, { isServer }) {
    config.module.rules.push({
      test: /\.svg$/,
      use: ['@svgr/webpack'],
    });
    return config;
  },
};

Is typescript, next config valid?

and below is my next build output log.

package.json

  },
}

As you can see here, .next is created but no .out. What could be wrong?

Follow the official documentation and change the name of the output directory.

/**
 * @type {import('next').NextConfig}
 */
const nextConfig = {
  output: 'export',
 
  // Optional: Change links `/me` -> `/me/` and emit `/me.html` -> `/me/index.html`
  // trailingSlash: true,
 
  // Optional: Prevent automatic `/me` -> `/me/`, instead preserve `href`
  // skipTrailingSlashRedirect: true,
 
  // Optional: Change the output directory `out` -> `dist`
  // distDir: 'dist',
}
 
module.exports = nextConfig
