Just installed the kafka-couchbase connectors plugin but I can’t get the connector to load as the connect build looks to be missing something and cannot find at least this class
com.couchbase.connect.kafka.handler.source.RawJsonMetadataSourceHandler
See the error below.

[2022-06-24 23:36:40,706] INFO Kafka Connect stopping (org.apache.kafka.connect.runtime.Connect:67)
I did the unzip and moved all the lib files to my Kafka plugins folder, and the etc files to my config folder. I didn’t see anything about other folders or things I need to install. Did I miss a step?
We’re using kafak version kafka_2.13-2.8.0 and the CB connector version 4.1.7
