Vite app failed to fetch a dynamically imported module

TypeError: Failed to fetch dynamically imported module

A Vite-built app tried to load a dynamic import chunk that was unavailable, blocked, or mismatched with the currently cached HTML.

TypeError: Failed to fetch dynamically imported module
  • The browser cached an older HTML file that still references deleted chunk names after a new deployment.
  • The network request for the chunk failed.
  • A browser extension blocked the dynamically imported module request.
  1. Handle dynamic import failures gracefully and consider reloading the page when a missing chunk is detected.
  2. Keep previous deployment chunks available for a transition period if users commonly have cached HTML.
  3. Test with browser extensions disabled and verify whether ad-blocking or privacy tooling is blocking the request.
