I encountered the same issue. Client Java: 3.3.5 TiKV: 7.3.0 TiUP Playground: 1.13.0

My code looks like this. Please let me know if there is something wrong with it. 

        TiConfiguration conf = TiConfiguration.createDefault("127.0.0.1:2379");
        try (TiSession session = TiSession.create(conf);
             RawKVClient kvClient = session.createRawClient()) {
            var iterator = kvClient.scanPrefix0(ByteString.copyFromUtf8("t"), 100, true);
            iterator.forEachRemaining(System.out::println);
        }
