----------------------------------
Hi [~zjshen]
In my experience, that kind of conversion between Long to Bytes to String to
Bytes to Long does not work. When an object is serialized as a Bytes.toBytes
(Long) , we cannot read it back as a Bytes.toString(). It has to be read back
as Bytes.toLong().
Is there any reason you need to use String to carry values across? Could you
use byte[] instead and then convert them back as appropriate?
thanks
