NewRealisClient method returning <nil> error when zookeeper leader not found

[biprade]

When Gorealis is not able to find Zookeeper leader (sample error response shown below), it does few retries. But if all the retries are unsuccessful, then the NewRealisClient method returns nil as error instead of any valid error.
