Version

pulsar server 2.10.0
pulsar-client-cpp 3.1.1
os redhat 8

Minimal reproduce step

1. create non persistence producer
2. create consumer and use subscribeWithRegex

I have used this on consumer side

consumer_config.setReceiverQueueSize(1000);
consumer_config.setAckGroupingTimeMs(5);
consumer_config.setAckGroupingMaxSize(60);

pulsar::BatchReceivePolicy policy(1000, -1,200);
m_Config.setBatchReceivePolicy(policy);

std::string regex_pattern_sub = "non-persistent://public/default/.*";
auto res = m_Client->subscribeWithRegex(regex_pattern_sub, sub_name, m_Config, m_Consumer);

What did you expect to see?

I expect regex should work for non persistent topic also as it is shown in documentation.

What did you see instead?

I don't see any coming messages

Anything else?
