Environment

DevTest 10.7.2 and above 

Cause

The error concerning the 'bytes' message is due to GRPC. If the message is of the 'bytes' type, the system attempts to distinguish between a 'bytes' message and a GRPC message

Resolution

We have a patch for 10.7.2.  Please refer to DE587359 when opening a ticket.
