I'm not sure but may be your elasticsearch cluster is secured and is using `https`? Could you reproduce the exact call done by your script using `curl`? And share the call and the response?

Below is the curl response :

```auto
Sunils-MacBook-Pro:kibana sunil$ curl -H "Content-Type: application/json" -XPOST "http://localhost:9200/sunil_test/_doc/optionalUniqueId" -d "{ \"customer_id\" : \"133\"}"

{"_index":"sunil_test","_type":"_doc","_id":"optionalUniqueId","_version":2,"result":"updated","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":3,"_prim

Are you sure that your script passes `-H "Content-Type: application/json"` as well?  
I think you could debug maybe that call and see what is the exact http request sent to Elasticsearch?

A `406` from Elasticsearch is almost always due to an incorrect content-type. I expect, if you expand the `body` of the response, it will tell you that.
