Quarkus and Redis

Im using REDIS to cache in Quarkus Application but sometimes I got an error saying that "Client is closed" when I try to access key/values from it.

WARN  [io.net.uti.con.AbstractEventExecutor] (vert.x-eventloop-thread-2) A task raised an exception. Task: io.vertx.core.http.impl.pool.Pool$$Lambda$1087/0x0000000801418c40@b245c25: java.lang.IllegalStateException: Client is closed

I have Injected redisClient in a singleton class and use it to get/create/delete cache.

My Redis class:

@Singletonpublic class Redis{        @Inject        RedisClient redisClient;    public String add(final String key, final String value) {        return redisClient.set(Arrays.asList(key, value)).toString();    }    public String get(final String key) {        return redisClient.get(key).toString();    }}

To access those methods I have Injected this class:

class XPTO {  ...  @Inject  Redis redis;  ...  public test() {    String cache = redis.add("allRegisters2", "abc");  }

Note:

• My Redis is running in docker all the time and I can access it via Redis explorer from Intellij.
• Sometimes I can access but on the second attempt the client connection is shutdown.

Any idea what is happening or a clue of what is causing the problem?
