debug
debug(
formatter?: (exchange: Exchange<Current>) => unknown,
options?: Record<string, never>,
): RouteBuilder<Current>
Sugar for .tap(debug(formatter)). Same shape as .log(), but the level is fixed to debug. Useful for verbose pipeline tracing that can be silenced via the logger configuration without removing the call.
// Debug log id, body, headers
.debug()
// Debug log a derived value
.debug((exchange) => ({ correlation: exchange.headers['x-correlation-id'], body: exchange.body }))
