Sample configuration for the MongoDB sink:

connector.class=org.apache.camel.kafkaconnector.mongodb.CamelMongodbSinkConnector
camel.sink.endpoint.operation=insert
camel.sink.endpoint.collection=testRecords
tasks.max=1
topics=org.apache.camel.kafkaconnector.mongodb.sink.CamelSinkMongoDBITCase
name=CamelMongoDBSinkConnector
value.converter=org.apache.kafka.connect.storage.StringConverter
camel.sink.path.connectionBean=mongo
camel.beans.mongo=#class:com.mongodb.client.MongoClients#create('mongodb://localhost:32772')
camel.sink.endpoint.database=testDB
key.converter=org.apache.kafka.connect.storage.StringConverter

An important bit for the mongoDB sink is to configure the camel.beans.mongo property correctly. In this case, it is setting the bean to be created by calling the method create passing the URL of the mongodb instance (mongodb://localhost:32772). This should be configured accordingly to your setup.
