# X_TEST_LIVE_NODE_EMPTY

## Means

the in-process sync node has no live query to serve

## Typical cause

the `subscribe` fixture built a node and found no `query({ live: true })` registered — almost always the app's api module was never imported, so `defineApi()` never named a query. A registry with nothing in it answers every subscribe with "no live query registered", which is a working socket serving no reads

## Fix

import the app's api module in the test preload, then `x queries list --json`
