Hey,  
elasticsearch source connector return:

> **This connector has failed**  
> This connector has failed. Try restarting the failed connector, or [check the logs](https://docs.confluent.io/platform/7.2.1/connect/logging.html) to understand why the connector has failed. You can also view the Confluent Developer troubleshooting guide to learn how to troubleshoot issues with connectors.
> 
> Restart failed connector

this is the setting:

```auto
{
  "name": "elastic-source",
  "config": {
    "name": "elastic-source",
    "connector.class": "com.github.dariobalinzo.ElasticSourceConnector",
    "tasks.max": "1",
    "errors.log.enable": "true",
    "errors.log.include.messages": "true",
    "es.host": "127.0.0.1",
    "es.port": "9200",
    "es.user": "elastic",
    "es.password": "sarindra",
    "index.prefix": "",
    "topic.prefix": "test"
  }
}

```

this url [https://localhost:9200/\_cat/indices?v](https://localhost:9200/_cat/indices?v) returns

```auto
> health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
> yellow open test R9t_ToRpQGyi_tTw6MdkSA 1 1 15 0 15.5kb 15.5kb
> green open kibana_sample_data_ecommerce tRcxyLrsSKuWcmOx3ZNKew 1 0 4675 0 4mb 4mb

```
