To fix this, add curl option -H ‘Content-Type: application/json’. This error is due to strict content-type checking introduced in ElasticSearch 6.0

curl -XPUT 'localhost:9200/products/mobiles/1?pretty' -d'
{
  "name": "iPhone 7",
  "camera": "12MP",
  "storage": "256GB",
  "display": "4.7inch",
  "battery": "1,960mAh",
  "reviews": ["Incredibly happy after having used it for one week", "Best iPhone so far", "Very expensive, stick to Android"]
}
'
Response
{
  "error" : "Content-Type header [application/x-www-form-urlencoded] is not supported",
  "status" : 406
}
