JavaScript Error

A single JavaScript error occurring anywhere in the session — not necessarily tied to a specific click — is enough for this tag; each error's details (message, file, line) are viewable in that session's Errors tab.

This metric gives you a comprehensive radar for the platform's technical instability without waiting for user complaints. Imagine you want a list of sessions that actually ran into a technical problem, even if the user never noticed; this tag gives exactly that list. Filtering on this signal is the fastest way to find real-world instances of a bug reported in the console, without manually reproducing it.
