title: Kafka Sink: ERROR Stopping due to error (org.apache.kafka.connect.cli.ConnectStandalone:130)
body: <p>Am trying to stream data from one stream file to another file. It was working earlier and suddenly it providing the error as <code>ERROR Stopping due to error (org.apache.kafka.connect.cli.ConnectStandalone:130)</code>. Have restarted the zookeeper, kafka-server, schema-registry, source and sink connectors, but still am facing same issue and unable to resolve it. Any suggestion would be helpful.</p>

  <pre><code>name=local-file-source
  connector.class=FileStreamSource
  tasks.max=1
  file=/home/jimmacaulay/Desktop/ETL/Kafka/confluent-5.5.1/data/data/Jim_Source.csv
