Could not store data in Redis data storage - Spring Boot

Question

I have a problem with storing data into Redis storage. Redis is dockerized. I have to mention that connection to Redis is successfully opened and querying data works perfectly fine - there is no issues at all but when I'm trying to store data the exception bellow occurs.

Exception:

org.springframework.data.keyvalue.core.UncategorizedKeyValueException: nested exception is java.lang.NullPointerException
at org.springframework.data.keyvalue.core.KeyValuePersistenceExceptionTranslator.translateExceptionIfPossible(KeyValuePersistenceExceptionTranslator.java:49)
at org.springframework.data.keyvalue.core.KeyValueTemplate.resolveExceptionIfPossible(KeyValueTemplate.java:484)

Model:

@RedisHash("TaskSubscriber")
public class TaskSubscriber implements Serializable {

    private static final long serialVersionUID = 20190329202800L;

    private String id;
    private String destination;
    private String username;

    @SuppressWarnings("unused")
    public TaskSubscriber() { }

    public TaskSubscriber(String sessionId, String destination, String username)
    {
        this.id = sessionId;
        this.destination = destination;
        this.username = username;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getDestination() {
        return destination;
    }

    public void setDestination(String destination) {
        this.destination = destination;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }
}

Repository:

@Repository
public interface TaskSubscriberRepository extends JpaRepository<TaskSubscriber, String> {

    List<TaskSubscriber> findAllByDestination(String destination);

    List<TaskSubscriber> findAllByUsername(String username);
}

In service class I'm just calling save method from TaskSubscriber repository passing TaskSubscriber model with data.

Does anyone have an idea how to fix this? Thank you in advance.

Does the exception have a root cause(s). That one looks like it might be lacking data. — Not a JD, Mar 29 '19 at 20:31
Here is the complete stack trace: https://www.heypasteit.com/clip/0IS923 — Heril Muratovic, Mar 29 '19 at 20:56
Spring Boot - 1.4.0.RELEASE Redis-Client: 2.9.0 spring-boot-starter-data-redis: 2.0.6.RELEASE — Heril Muratovic, Mar 29 '19 at 21:01
Spring Boot 1.4.0 but Redis Starter 2.0.6? I would think both of those should be the same version, no? — Not a JD, Mar 29 '19 at 21:07

@HerilMuratovic , can you please share your redis configuration and redis logs when this exception comes. — Anuj Vishwakarma, Apr 01 '19 at 06:43
I have tried with RedisTemplate instead of RedisRepository and everything works fine. — Heril Muratovic, Apr 01 '19 at 22:16
