-------------------------------
Description:
Found the following logs in tests
{code:java}
java.lang.NullPointerException: omNode-2@group-523986131536->omNode-1: Previous
TermIndex not found for firstIndex = 93 at
java.base/java.util.Objects.requireNonNull(Objects.java:360) at
org.apache.ratis.server.leader.LogAppenderBase.assertProtos(LogAppenderBase.java:270)
at
org.apache.ratis.server.leader.LogAppenderBase.newAppendEntriesRequest(LogAppenderBase.java:255)
at
org.apache.ratis.grpc.server.GrpcLogAppender.appendLog(GrpcLogAppender.java:387)
at
org.apache.ratis.grpc.server.GrpcLogAppender.run(GrpcLogAppender.java:262) at
org.apache.ratis.server.leader.LogAppenderDaemon.run(LogAppenderDaemon.java:80)

It might not be expected to throw NPE.
