Indexing failure when using bulk API

Experienced an error while indexing content from drupal to elasticsearch installed on same VM. Noticed two things from elasticsearch logs below:

  • failed to parse, document is empty.
  • 'defaiya_articles_alias' alias which i think it was created automatically on first bulk operation occured.

Am using Elasticsearch 1.7.4 along drupal module elasticsearch_connector-7.x-1.0-alpha9

This happens when posting with Bulk endpoint localhost:9200/defaiya_articles/defaiya_articles/_bulk?refresh=1

I have no clue about whats happening but i know am missing some configuration on elasticsearch. That because drupal module was working fine with a trial service from found.elasic.co.
