Hi,

What this response means:  
{  
"error":  
"ElasticSearchParseException[Failed to derive xcontent from (offset=0,  
length=0): []]"  
,  
"status":400  
}

while getting a document by ID from Elastic search ?  
I get this error when getting the document after other ES query calls. I  
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.  
Best regards.

Hi,

I found the problem, I was sending GET request as POST by mistake.

Best regards.
