> Suppress incorrectly passes a null topic to the serdes
> ------------------------------------------------------
>
> Key: KAFKA-8254
> URL: https://issues.apache.org/jira/browse/KAFKA-8254
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 2.1.0, 2.2.0, 2.1.1
> Reporter: John Roesler
> Assignee: John Roesler
> Priority: Major
> Fix For: 2.3.0, 2.2.1
>
>
> For example, in KTableSuppressProcessor, we do:
> {noformat}
> final Bytes serializedKey = Bytes.wrap(keySerde.serializer().serialize(null,
> key));
> {noformat}
> This violates the contract of Serializer (and Deserializer), and breaks
> integration with known Serde implementations.
