Vert.x Redis Question About IndexOutOfBoundsException - redis

Question

I encountered a problem when using the Redis client of the vert.x , I would frequently update Redis when the concurrency was high, but an exception was reported
java.lang.IndexOutOfBoundsException: null

The version I use is vertx-redis-client: 3.8.5,and my code is:
redisApi.hset(getList("key724762801283102234",sn,status) ,result ->{
if(result.succeeded()){
logger.info("success);
}else {
logger.error("failed");
}
});
So is there any problem here? thank you very much
