    Description

      Maybe this is not a bug, but it looks like something is wrong. This didn't happen in kafka streams 2.2.

       

      Applying an aggregate() with suppress on kafka 2.3 sends nulls into Serializer if delayed msgs are received.

      Not sure if some data is lost or not(yet). But IMHO getting a null to serialize the "accumulator" object is suspicious that something is wrong.

       

      Attached java code to demonstrate it.

      With kafka 2.3 -> LongSerde prints NULL, not in kafka 2.2
