Hi,

Hi, I am using 7.17.3 stack for elastic. Low level Elasticsearch rest client is from 7.15.2  
I am trying to send a payload having special characters in it using the below code.

Request request = new Request("PUT", ELASTIC\_ENDPOINT + elasticUniqueID);  
request.setEntity(new NStringEntity(message, ContentType.APPLICATION\_JSON));

I am some time getting this error -  
ine [HTTP/1.1 400 Bad Request]  
{"error":{"root\_cause":[{"type":"mapper\_parsing\_exception","reason":"failed to parse"}],"type":"mapper\_parsing\_exception","reason  
":"failed to parse","caused\_by":{"type":"i\_o\_exception","reason":"Unexpected character (',' (code 44)): expected a value  
n at [So  
urce: (ByteArrayInputStream); line: 1, column: 2803]"}},"status":400}

How I can write any type of string using the simple JSON object?

It seems its trying to combine 2 jsons while sending request and hence getting , between those 2 jsons. How I can force it to post single json at a time?
