AWS Api Gateway Post to DynamoDB

Question

i need help with Response Body Template. I am Using POST to "PutItem" in dynamoDB using APIGateway directly(No lambda).

The new item is added successfully but the response is Empty at 200

What I need is 1 - New row data 2 - Status 3 - Message

{
  "data": [],
  "status": "Success",
  "message": "Updated Succesfully"
}

without using lambda...Is this possible?

I tried many stuffs i.e.

#set($inputRoot = $input.path('$'))
{"templateId": "$elem.templateId.S",
"templateFileName": "$elem.templateFileName.S"}

but its showing null.

Here is my log when i run Test @API Gateway
