Getting "Unknown Reply" while connecting GCP redis instance from jedis java client

Question

I am getting the below error while trying to test the Redis memory-store GCP service. The mememory-store service works fine in GCP but I can not store any data.

I am using jedis client and when I run the below code, the connection gets established with the Redis instance but it always returns the strange character.`

JAVA Code-

JedisPool pool = new JedisPool("XXX.XX.XX.149", 6378);
    try (Jedis jedis = pool.getResource()) {
        Map<String, String> hash = new HashMap<>();
        hash.put("name", "John");
        hash.put("surname", "Smith");
        hash.put("company", "Redis");
        hash.put("age",   "29");
        jedis.hset("user-session:123", hash);
        System.out.println(jedis.hgetAll("user-session:123"));
    }

Exception -
