title: Kafka Salesforce sink connector - The Kafka record is missing the key _ObjectType which is used to identify the SObject
body: <p>I am using confluent cloud to sink some data from Kafka to Salesforce via SObject Sink connector. The connection is made but I am running into an error &quot;The Kafka record is missing the key _ObjectType which is used to identify the SObject. Please include the _ObjectType field in the record&quot;. Anyone has an idea of what is going wrong error?</p>
  <p>Google searches aren't that useful as they lead me to Kafka Key/Value concept which is primarily for maintaining order of the messages</p>
