When trying to connect to Salesforce Case Push Topic using Salesforce Kafka Connector getting Error

Question

When object is set as 'Case' instead of the default 'Lead' in salesforce-example.properties the connect stand alone gives the following error.

ERROR WorkerSourceTask{id=salesforce-0} Task threw an uncaught and unrecoverable exception (org.apache.kafka.connect.runtime.WorkerTask:177)
