Question

I am trying to create a connector using debezium connector to postgresql and kafka connect. But am seeing this error

[2020-12-31 21:52:20,251] ERROR Producer failure (io.debezium.pipeline.ErrorHandler:31)
java.lang.RuntimeException: java.lang.BootstrapMethodError: java.lang.NoClassDefFoundError: org/apache/kafka/connect/header/ConnectHeaders

I tried testing the status of the connector. It says status failed with the same error as above.

Connect Headers were added in Kafka 1.1.0 with KIP-145

According to the comments, you're using Kafka 1.0.2
