Hi @AWSDeven & @grzegorzewald , Where did you find the sample config? Are you sure the config that you are using is valid for the ES loader version you are using. As I can see from the documentation the configuration seems to be bit different of what you are using here. It does not have kinesis and nsq section present in the example config here - https://raw.githubusercontent.com/snowplow/snowplow-elasticsearch-loader/master/examples/config.hocon.sample
I am using snowplow_elasticsearch_loader_http_0.10.2.jar, I received the same error on running with which you have started this thread. I added the kinesis & nsq section in my config and it worked. But whenever I try to push data to kinesis stream it crashes, refer the link here - Unable to connect ELK stack on aws from Elasticsearch Loader
