AWS API gateway and elastic search get query - amazon-web-services

Question

I need to call elastic search engine directly from api gateway using http connection eg.
https:////_doc/_search?pretty&filter_path=hits.hits._source
i have n number of orders in elastic search engine which i want to get using get query ,but i want only array of json i posted and dont want any other information in the response.how can i do that ?
eg.
this is what i am getting :
{
"hits" : {
"hits" : [
{
"_index" : "gpss_orders",
"_type" : "_doc",
"_id" : "4867254",
"_score" : 1.0,
"_source" : {
"orderId" : 4867254,
"loadId" : 18214,
"orderTypeId" : 1
}
]
}
}
But i would want response something like this :
[ {
"orderId" : 4867254,
"loadId" : 18214,
"orderTypeId" : 1
}]
do i need to change in api gateway method response?
i changed the api gateway method response template and got the expected out
#set($esOutput = $input.path('$.hits.hits'))
#set($orders = [])
#foreach( $elem in $esOutput )
#set($order = $elem["_source"])
#set($response = $orders.add($order) )
#end
$orders
but now the problem i am facing is that though response from elastic search engine is the proper json,response after method integration template update become like this without any braces :
[{orderId=4867254, loadId=18214, orderTypeId=1, orderTypeName=Fuel}]
response from elastic search :
"took" : 1,
"hits" : {
"hits" : [
{
"_id" : "4867254",
"_score" : 1.0,
"_source" : {
"orderId" : 4867254,
"loadId" : 18214,
"orderTypeId" : 1,

There isn't a way to shape the return object from elasticsearch. Depending on how you access this data, you could have your own server-side code as a proxy make the query and remove extraneous information before returning it to the clients. A bonus is you can use the proxy to decide what information to return depending on factors such as permissions, caching or rate-limiting, etc.
