Добрый день, играю с однозначностью и не вступаю в переписку. Использование этого маршрута отлично подходит для маршалинга в список, но использование параметра asMap=true завершается ошибкой с исключением Nullpointer. Есть ли что-нибудь очевидное, чего не хватает? В настоящее время используется Spring Boot 2.5.5 и Apache Camel 3.12.0.

 @Override public void configure() {   log.info("StartApplication...Camel");    UniVocityCsvDataFormat dataFormat = new UniVocityCsvDataFormat()  .setNullValue("N/A")  .setLazyLoad(true)  .setAsMap(true);  from("file://source/?idempotent=falseamp;delete=false")  .startupOrder(1)  .autoStartup(true)  .routeId("read-csv")  .log("Filename:${file:name}")  .unmarshal(dataFormat).split().body()  .log("${body}");  log.info("StopApplication...Camel");   }  

Это ошибка, показанная с помощью asMap=true, но она работает с asMap=false.
