Painless Script update fails to actually update the document

I have a document in ES. A field named "site" which is currently having value as "Elasticsearch". I want to update the value of this field to "stackOverFlow". I am using below script for the same.

"script": { "lang": "painless", "inline": "for (k in params.keySet()){if (!k.equals('ctx')){ctx._source.put(k, params.get(k))}}" }, "params":{ "site":"stackOverFlow" }

I am getting success in my response and the _version is getting increased by 1. But still my document is not getting updated. The value of site remains as "Elasticsearch".

NOTE : I am using ES version 6.4

Can anyone help me in figuring out where it goes wrong??

"params" field should be included within the script. Move the braces before "params" to the end.

Below ES query works for me!

POST /itest/_doc/1/_update
{
  "script": {
    "lang": "painless",
    "inline": "for (k in params.keySet()){if (!k.equals('ctx')){ctx._source.put(k, params.get(k))}}",
    "params": {
      "site": "stackOverFlow"
    }
  }
}
