It might have been fixed via

Hi all,

I believe I've found a bug in Kafka Streams when:

- Running an app in EOS
- Calling KeyValueStore::delete(...) on a nonexistent key
- Can cause a ProducerFencedException

The expected behavior is that the call to delete() returns null (as per
the
javadoc) and doesn't cause a ProducerFencedException.

I've created a minimally reproducible example which reliably produces the
bug on my own environment at this repository:

https://github.com/littlehorse-eng/kafka-punctuator-fencing-issue

Could someone please take a look and let me know if you can reliably
reproduce it on your end as well, and if so, how to file a bug?

Thank you,
