Q:

File downloaded from Camel Rest is empty

I'm trying to let users download a text file from my camel application. The trouble is, is that the file contains 0 bytes (should be 435b and is in the debugger).
Could someone look at the code and advise?

@Component
public class CalendarRoute extends ExceptionHandlingRoutes {

  @Autowired
  private CalendarService calendarService;

  @Override
  public void configure() {
    super.configure();
    rest("/calendar").description("Foo calendaring")
        .produces("plain/text")
        .get("/").description("accepts data to create an ics file with")
        .to("direct:getIcs");

    from("direct:getIcs")
        .process(getIcs());
  }

  private Processor getIcs() {
    return exchange -> {
      exchange.getIn().removeHeader("Content-Length");
      exchange.getIn().setHeader("Content-Type", MediaType.parseMediaType("text/calendar"));
      byte[] file = calendarService.generateCalendarFile();
      exchange.getIn().setBody(file);
    };
  }
}
