Error click
An error click is a click that coincides with a JavaScript error or a failed request, connecting a user's action directly to a technical failure. It answers the debugging question "what did the user do to trigger this" without reproduction work, because the trigger and the error are recorded together.
How it works
Detection joins two streams: interaction events from the recording and errors from the console or an error tracker, matched by timestamp and session. rrweb's console plugin can record console output into the same event stream, and custom events (see custom event) let error trackers drop markers at exception time. The result is a queryable link: every session where a click within N milliseconds preceded an uncaught exception. That query, run across all sessions, ranks which UI elements are generating errors in production and how many users each one hits.
Where you encounter it
Error triage workflows, where "sessions with error clicks" is the shortlist worth watching, and impact scoring, where user-facing errors get prioritized over background noise.
