As the following script shows:

```auto
  "script": {
    "inline": "ctx._source.users.remove(params.users)",
    "params": {
      "users": 400903
    }
  }

```

ES complains about `index_out_of_bounds_exception` which it calls `remove(int)` but I need it call `remove(Object)`, how to achieve it? Many thanks.

The Painless API is described here ([https://www.elastic.co/guide/en/elasticsearch/painless/6.2/painless-api-reference.html](https://www.elastic.co/guide/en/elasticsearch/painless/6.2/painless-api-reference.html)). List only contains remove(int) as you have mentioned. The reasons for the way method overloading works in Painless are described here ([https://www.elastic.co/guide/en/elasticsearch/painless/current/modules-scripting-painless-dispatch.html](https://www.elastic.co/guide/en/elasticsearch/painless/current/modules-scripting-painless-dispatch.html)).

My suggestion would be to rewrite the script as the following:

```auto
ctx._source.users.remove(ctx._source.users.indexOf(params.users))

```
