# X_LIVE_CLIENT_MISSING

## Means

retired in 21.0.0 (no LiveClient to register; see X_REALTIME_UNINSTALLED): a realtime hook ran in a browser with no LiveClient registered

## Typical cause

**registered, thrown by nothing since 21.0.0.** There is no `LiveClient` to register: the island bootstrap installs realtime, and a hook in a bundle that never did is `X_REALTIME_UNINSTALLED`

## Fix

delete any branch matching this code, because it never runs. For the failure it used to name, see `X_REALTIME_UNINSTALLED`
