router.persist() found no usable IndexedDB (a non-browser runtime, private mode, or blocked storage); the router runs in-memory with no durable resume. Pass { storage } to use another backend.

Data Router

Since

1.40.0

What happened

Persistence was asked for and no IndexedDB could be opened - a non-browser runtime, a private window, or storage blocked by policy. The router keeps working entirely in memory: nothing is saved, and a reload starts from scratch instead of resuming.

The fix

Supply your own storage object with get/set (localStorage, a server round-trip, anything), or accept the in-memory behaviour.

The smallest fix

router.persist({ storage: { get: (k) => …, set: (k, v) => … } });
