Hi Yes if the body is a byte array and you have binary=true on the FTP then it sends the data as raw bytes.
To enable TRACE logging you need to change the logging configuration in the message broker. So it may have a log4j.properties or something similar where this can be tweaked and then restart the broker. Also for the stacktrace then it helps if you show the entire stacktrace and not only the message.
