> When the *@Context SseEventSink sseEventSink* parameter is added to the method, logs are no longer displayed in it. For example, there are some exceptions that are visible only during debugging, but there are no logs from them. Regular logging via the *LoggerFactory.getLogger* doesn't work in this case either.
