404: NOT_FOUND

The Vercel deployment has no file or route at this path

Seen in Vercel

The deployment exists, but nothing in its build output or routes matches the requested path.

Common causes

  • A single-page app route with no rewrite to index.html.
  • The wrong output directory or framework preset, so the deployment is missing files.
  • A path that differs in case from the file name.

How to fix it

  1. For single-page apps, add a rewrite in vercel.json: {"rewrites": [{"source": "/(.*)", "destination": "/index.html"}]}
  2. Check the project's framework preset and output directory, then redeploy.
  3. Inspect the deployment's Source and Output tabs to see which files were built.
