> We encountered a RaftRetryFailureException carrying a very long error stack. The root cause showed that RaftClientRequest.message was null. We first suspected that we passed a null message to RaftClientRequest. However, we then discovered that this NullPointerException happened during the 2rd retry attempt, not the 1st attempt. So the problem probably lies in Ratis. Full error stack is attached.  [~szetszwo] Could you please take a look at this? Thanks in advance!
