I followed below steps.

1. Clone this project and create a jar using command mvn clean package -DskipTests
2. There are two jar is created. first one is elastic-source-connect-1.5.5.jar and second is elastic-source-connect-1.5.5-jar-with-
   dependencies.jar.
3. Copied first jar(elastic-source-connect-1.5.5.jar) into kafka/libs folder
4. Restart Kafka
5. Start connector by following command-
   bin/connect-distributed.sh config/connect-distributed.properties
6. Hit following api Curl
   curl --location 'http://localhost:8083/connectors' \ --header 'Content-Type: application/json' \ --data-raw '{ "name": "elastic-connector", "config": { "connector.class": "com.github.dariobalinzo.ElasticSourceConnector", "tasks.max": "1", "es.host": "99.99.99.120", "es.port": "9200", "index.prefix": "employee", "topic.prefix": "data", "incrementing.field.name": "timestamp" } }'

Now it gives following error.
