Custom command with Lettuce occurs UnsupportedOperationException

Bug Report

Current Behavior

I am trying to use the lettuce library to execute a custom command with implements ProtocolKeyword interface. However, after execution, an java.lang.UnsupportedOperationException: io.lettuce.core.output.StatusOutput does not support set(long) exception occurs.

Stack trace

Input Code

- implemented custom command ```java import java.nio.charset.StandardCharsets; import io.lettuce.core.protocol.ProtocolKeyword; public enum Tile38Command implements ProtocolKeyword { NEARBY, SEARCH, WITHIN, INTERSECTS; private final byte commandBytes[]; Tile38Command() { commandBytes = name().getBytes(StandardCharsets.UTF_8); } @Override public byte[] getBytes() { return commandBytes; } } ``` - main class ```java public static void main(String[] args) throws Exception { RedisURI uri = RedisURI.Builder.redis("10.177.189.59", 6397).build(); RedisClient client = RedisClient.create(uri); StatefulRedisConnection connection = client.connect(); RedisCommands sync = connection.sync(); StringCodec codec = StringCodec.UTF8; StopWatch stopWatch = new StopWatch("tile38"); stopWatch.start(); CommandArgs commandArgs = new CommandArgs<>(codec) .add("am_emd_a_a") .add("POINT") .add(35.179816) .add(129.075022); System.out.println(commandArgs.toCommandString()); String result = sync.dispatch(Tile38Command.INTERSECTS, new StatusOutput<>(codec), commandArgs); stopWatch.stop(); System.out.println(stopWatch.prettyPrint()); } ```

Expected behavior/code

execute custom command and receive resutls.
when custom command executes redis client, result is like below.

10.177.189.59:6397>  intersects am_emd_a_a POINT 35.179816 129.075022
1) (integer) 0
2) 1) 1) "2647069000"
      2) "{\"type\":\"Feature\",\"geometry\":{\"type\":\"MultiPolygon\",\"coordinates\":[[[[129.073100795,35.179060681],...,[129.073100795,35.179060681]]]]},\"properties\":{\"admcode\":\"2647069000\",\"mid\":618}}"
