Q016
A request used the database while it was down, or a migration it needs failed (503; the server log has the driver's error). Pages that run no statements still serve.
Fix: Start the database and check DATABASE_URL, or fix the migration: the next statement tries again.
Status in kerf@0.1.0: reported by @kerf-js/start when it serves or renders the route, and by kerf check and kerf routes --meta.
More: kerf docs start.
