It's working fine with Kafka 2.0.1. The potential root cause of this issue is in Kafka 2.1.0 added MultiOp request and response in ZookeeperClient. Please refer https://issues.apache.org/jira/browse/KAFKA-6082.(Relevent commit - apache/kafka@297fb39)
I can see in PR - #57 initial multiop support added for zetcd. However, it's broken for Kafka 2.1.0

While I don't see the NPE, kafka is not able to elect a leader for me:

I am able to get Kafka 2.1.0 to work correctly if I swap out etcd 3.3 and zetcd 0.0.5 for Zookeeper 3.4, keeping all settings identical.

zketcd: fixed bug causing hidden multi-op error
876e4c2 
zkResponse was hiding multi-op error in partial response,
added new response with error function.  Also, fixed test
to expect correct errors instead of api errors

zetcd: fix encoding of multiop errors
734e285 
The current multiop implementation was not properly encoding a single error
in a multiop request.  If op 1 succeeds, but op 2 fails, then zookeeper
should return two responses, one success and one failure of type -1.
