Details page calls useOnlineBoard to populate the sibling mini-list, passing empty-string params when the URL has no ?request=... context. The empty params were reaching the backend as dateFrom=&dateTo=, which returns HTTP 400 and surfaces as an error in the browser console. Short-circuit the effect so we just emit an empty result when either range bound is missing — same no-fetch behavior, no console noise.
