Remove elements/objects From Array in ElasticSearch Followed by Matching Query

[sandip179 (Sandip)]

I have below types documents.

  {
      "_index": "example1",
    "_type": "doc",
    "_id": "8036",
    "_score": 1,
    "_source": {
      "user": "kimchy8036",
      "postDate": "2009-11-15T13:12:00",
      "locations": [
        [
          72.79887719999999,
          21.193036000000003
        ],
        [
          -1.8262150000000001,
          51.178881999999994
        ]
      ]
    }
  } 

And below is mapping:

 {
   "example1": {
      "mappings": {
      "doc": {
      "properties": {
      "locations": {
        "type": "geo_point"
        },
        "postDate": {
         "type": "date"
       },
         "status": {
          "type": "long"
        },
          "user": {
          "type": "text",
          "fields": {
            "keyword": {
             "type": "keyword",
             "ignore_above": 256
              }
            }
          }
       }
      }
     }
   }
 }

I can add multiple locations using below query.

    POST /example1/_update_by_query
 {
     "query": {
         "match": {
             "_id": "3"
               }
        },
         "script" : {
           "lang":"painless",
                    "inline": "ctx._source.locations.add(params.newsupp)",
                    "params":{
                                "newsupp":[-74.00,41.12121 ]
                                   }}
                       }

But not able remove array objects from locations. I have tried below query but not working.

       POST example1/doc/3/_update
       {
           "script" :
               {
               "lang":"painless",
               "inline":"ctx._source.locations.remove(params.tag)",
               "params":{
                     "tag":[-74.00,41.12121]
          }
        }
      }

Kindly let me know where i am doing wrong here. I am using elastic version 5.5.2
