ElasticSearch scripting set an object value-CodePudding

I am trying to use a script to set several values of my Elastic document.

POST myindex/_update_by_query
{
   "script" : {
      "source": """
        ctx._source.categories='categories';
        ctx._source.myObject={};
        """,
      "lang": "painless"  
    },
    "query": {
        "term" : {
            "name": "Tony"
        }
    }
}

But I can't set an object value with this painless language. However I write it, I get an error. Is there a way to do this, maybe with a different script language ?

Thanks!

In order to create an object (i.e. a hash map), you should do it this way:

    ctx._source.myObject = [:];
