Same is code is working with redis-server version "3.2.6".

4.3.2

Do you have a reproducer?

package com.example.starter;

import io.vertx.core.*;
import io.vertx.redis.client.Redis;
import io.vertx.redis.client.Request;
import io.vertx.redis.client.Response;

import static io.vertx.redis.client.Command.HGETALL;

public class MainVerticle extends AbstractVerticle {

  @Override
  public void start(Promise<Void> startPromise) throws Exception {

    io.vertx.redis.client.RedisOptions publisherRedisConfig = new io.vertx.redis.client.RedisOptions();
    String connectionString = "redis://localhost:6379";
    publisherRedisConfig.setConnectionString(connectionString);
    Redis publisherRedis = Redis.createClient(Vertx.currentContext().owner(), publisherRedisConfig);
    final Request req = Request.cmd(HGETALL);
    req.arg("PROD-SUPPORT.Interface.PROVIDERS_7773");
    publisherRedis.send(req, handler->{
      if(handler.succeeded()){
         Response response = handler.result();
        Object getResult = response.get(1);
        System.out.println(getResult.toString());
      }
    });

  }

}

Steps to reproduce

1. Add hash in redis having redis-server version 6.2.5.
2. try to access this hash with hgetall with the above reproducer
3. You will get the exception java.lang.RuntimeException: Multi is a Map
4. downgrade redis-server version to 3.2.6 then you will not get exception.

Extra

• Anything that can be relevant such as OS version, JVM version
• Java version amazon corretto 17 (Issue is not specific to java version)
• Mac os monterey 12.5.1
