I am learning elasticsearch. I have specified the mapping in \'mapping.json\'. Its contents are

{
    \"book\" : {
         \"_index\" : {
             \"enabled         


        

Answer 1

On AWS I got an error like

{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}

To fix it I added

-H 'Content-Type: application/json'
