What this response means:
"ElasticSearchParseException[Failed to derive xcontent from (offset=0,
while getting a document by ID from Elastic search ?

use HTTP keep-alive for ES requests.
I am pretty sure that I did something wrong at my client implementation end
but I have to figure out what this error means to find the problem
Thanks for any help.
