{method}() needs a buffered window; call router.buffer({ window, max }) first to record one.

data-router:no-buffer

Raised by

Data Router

Since

1.32.0

What happened

A time-travel method was called on a router that is not recording. Nothing is buffered, so there is no history to seek into, and the call did nothing. Buffering is opt-in because it is the only feature that makes the router hold on to deltas.

The fix

Call router.buffer() - with a window (milliseconds) or a max (number of deltas) - before using the time-travel API.

The smallest fix

router.buffer({ window: 300000 });
