/blog/tag/[tag]/ does not show on Vercel, but works on local prod.

Bug description

Running Next 14.
When invoking process.cwd() like

export async function getBlogPosts(
  blogDirectory: string = BLOG_CONTENT_PATH
): Promise<Optional<PostData[]>> {
  console.log(
    'Invoked all blog posts from: ' + path.join(process.cwd(), blogDirectory)
  );
  return getMDXData(path.join(process.cwd(), blogDirectory));
}

I get this on vercel

Invoked all blog posts from: /var/task/public/blogs
Invoked all mdx data from: /var/task/public/blogs

This solved it

/** @type {import('next').NextConfig} */

const nextConfig = {
  experimental: {
    outputFileTracingIncludes: {
      '/blog': ['./public/**/*'],
    },
  },
}
