# X_NOT_FOUND

## Means

no row for that id

## Typical cause

stale id, wrong tenant, or already deleted — or a `single: true` query's `GET /_x/query/<name>` whose `sql` matched no row (404; fix: `x queries show <name> --json`)

## Fix

confirm with `psql "$DATABASE_URL" -c "select id from <table> limit 5"` — `x db` has no `query` subcommand
