> Cast operation on a field of type bytes to a string returns the default ByteBuffer representation, not the content. For example, a field called "payload" of type bytes transformed in this way:
> payload:string
> Returns the result 
> "payload":\{"string":"java.nio.HeapByteBuffer[pos=0 lim=4 cap=4]"}
> We propose instead to represent the byte array as a hex string
> "payload":\{"string":"FFEEDDAABB123F"}
