Does Vertx 3.9.0 supports Redis Json or not? Any other ways to achieve it?

I am working with Vertx 3.9.0, I am trying to get json data for a key from redis Server.

redisConnection.send(Request.cmd(Command.GET).arg(key), handler->{  if(handler.succeeded()) {    Response response = handler.result();    System.out.println(response.toString());    promise.complete();  }else {    System.out.println(handler.cause());  }});

I always get WRONGTYPE Operation against a key holding the wrong kind of value

I am wondering whether Redis Json Support is provided by vertx-redis-client:3.9.0 ?If not then what are the alternatives to query Json data from Redis.
