same Set command works fine after connecting with redisConnect(), while it fails when i connnect in Non blocking mode using redisConnectNonBlock().

redisContext *rContext=nullptr:
rContext = redisConnectNonBlock(_redisIP.c_str(), stoi(_redisPort.c_str()));

if (rContext != nullptr && rContext->err)
{
	cout << "Unable to connect to Redis Server, Error: " << rContext->errstr << endl;
	exit(1);
}
else
{
	cout << "Connected to Redis Server" << endl;
}



//Set command func

redisReply* reply = nullptr;

unique_lock<mutex> redisLock(m_mutexRedisPush);

/* Write into Redis */
chrono::steady_clock::time_point begin = chrono::steady_clock::now();



void insertIntoRedis(string key, string json_data)
{
redisReply* reply = nullptr;
reply = (redisReply*)redisCommand(rContext, "SET %s %s", key.c_str(), json_data.c_str());
if (reply)
{
	if (strcmp(reply->str, "OK") == 0)
	{
		isInsertSuccessfull = true;
		cout << "JSON.SET successful for key " << key << endl;
	}
	else
	{
		cout << "JSON.SET failed for key " << key << ", Error" << reply->str << endl;
	}
	freeReplyObject(reply);
}
}

In blocking mode rCOntext->errStr returns null while reply returns "OK".
But In non-blocking mode the rContext->errStr and reply both are returning NULL after set command. please suggest what I did wrong here.
