@agriff  I did not know that you were using the Apache NiFi 2.x release.   The component list I provided is from the Apache NiFi 1.x release. NiFi 2.x switched from having numerous client version Kafka based processors to single Kafka based processors that now use a KafkaConnectionService controller service  component to define the kafka client version.  In Apache NiFi the only connection service included is for theKafka 3 Client.  The Kafka client 3 I understand to be backwards compatible to Kafka 2.6, but sounds like you are having success with using it for Kafka 2.5. Glad to hear you were able to resolve yoru underlying schema issue. Setting Bulletins level on a processor has absolutely nothing to do with log levels written to the nifi-app.log.  It only controls what level bulletins are created within the NiFi UI.  To change logging within the NiFi logs, you will need to modify the logback.xml configuration file found in the NiFi conf directory.  Please help our community grow.
