Browser

ChunkLoadError: Loading chunk app/page failed.

What it means
The browser tried to load a piece of your app's code that was rebuilt or replaced since the page was opened.
Likely causes
  • A new deployment went live or .next was rebuilt while the browser tab stayed open on an older version.
  • The .next cache folder on your computer got out of sync after switching branches.
Prevention
Refresh your browser tab after switching branches or restarting the local server.

Copy for your agent

I get `ChunkLoadError` in the browser. Hard-refresh the page, and if it still happens locally, stop the server, clear the `.next` build cache, and restart `npm run dev`.
