Elasticsearch through 400 bad request error

Hi,

I am getting 400 bad request for some JSON data when I pushed 700 JSON in Elasticsearch from ACE queue. But I am able to push same JSON data through curl command.

REST API
POST http://xx.xx.xx.xx:xxxx/index-name/_doc
This is my REST API.

Thanks

What is ACE queue?

ACE application has its own queue.
