> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Reporter: Greg Harris
> Assignee: Greg Harris
> Priority: Major

> When applying the {{Flatten}} transformation to a tombstone event, an exception is raised:
> {code:java}
> org.apache.kafka.connect.errors.DataException: Only Map objects supported in absence of schema for [flattening], found: null
> {code}
> Instead, the transform should pass the tombstone through the transform without throwing an exception.
