NullPointerException while caching collection - Rset

[navinvasu]

Expected behavior
No errors or Null pointer exception when Caching RSet. Collection of class-objects are saved to cache.

Actual behavior
Inconsistently throws NullPointer exception.
java.lang.NullPointerException: null at o.redisson.command.RedisExecutor.handleError(RedisExecutor.java:602) at o.redisson.command.RedisExecutor.execute(RedisExecutor.java:202) at o.r.command.CommandAsyncService.async(CommandAsyncService.java:564) at o.r.command.CommandAsyncService.writeAsync(CommandAsyncService.java:522) at org.redisson.RedissonSet.addAllAsync(RedissonSet.java:317) at org.redisson.RedissonSet.addAll(RedissonSet.java:305)

Steps to reproduce or test case
val cacheRSet = redissonClient.getSet(key, TypedJsonJacksonCodec(CacheRecord::class.java, objectMapper))
cacheRSet.addAll(listOf(Object))
cacheRSet.expire(cacheTtl)

Redis version
ElastiCache engine version 7.1.0

Redisson version
3.26.0

Redisson configuration
useClusterServers() timeout = 30000 isCheckLockSyncedSlaves = false

Unable to reproduce. Below is the test

        RSet<String> cacheRSet = redisson.getSet("key", new TypedJsonJacksonCodec(String.class, new ObjectMapper()));
        cacheRSet.addAll(Arrays.asList("1", "2", "3"));
        cacheRSet.expire(Duration.ofSeconds(1));

Is there any update?

[navinvasu]

@mrniko the error occurs Inconsistently. Would be difficult to reproduce.
Just an observation, the data type used was a java class vs the string used in the above example. Not sure if it has any impact on the way the redisson client reads the data and throws null pointer ?
