-------------------------------------
Summary: InsertField transformation fails when encountering
tombstone event
Key: KAFKA-8523
URL: https://issues.apache.org/jira/browse/KAFKA-8523
Project: Kafka
Issue Type: Bug
Components: KafkaConnect
Reporter: Gunnar Morling
When applying the {{InsertField}} transformation to a tombstone event, an
exception is raised:
{code}
org.apache.kafka.connect.errors.DataException: Only Map objects supported in
absence of schema for [field insertion], found: null
at
org.apache.kafka.connect.transforms.util.Requirements.requireMap(Requirements.java:38)
at
org.apache.kafka.connect.transforms.InsertField.applySchemaless(InsertField.java:138)
at
org.apache.kafka.connect.transforms.InsertField.apply(InsertField.java:131)
at
org.apache.kafka.connect.transforms.InsertFieldTest.tombstone(InsertFieldTest.java:128)
{code}
AFAICS, the transform can still be made working in in this case by simply
building up a new value map from scratch.
