Solutions

1. Use a browser that supports IndexedDB.
2. If IndexedDB is disabled (e.g. private browsing), enable it or accept degraded caching of dynamic imports.

When it happens

Trigger: Thrown when the dynamic-import cache is used in a browser without IndexedDB support.

Common situations: Private browsing modes or old browsers where indexedDB is unavailable or disabled.
