Hi there!

I'm trying to loop over a geo\_point array in my painless script, but I can't find a way to make it work.  
My script is called in a [script\_score stage](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html#function-script-score).

Here is the part of code not working :

```auto
for (def i=0; i < doc['locations'].values.length; i++) {
    distance = Math.min(distance, doc['locations'].values[i].arcDistance(lat, lon) * 0.001);
}

```

And here's what I get :

```auto
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
      "distance = Math.min(distance, doc['locations'].values[i].arcDistance(lat, lon) * 0.001); }",
      " ^---- HERE"
],

```

I also have this :  
`"reason": "Unable to find dynamic method [arcDistance] with [2] arguments for class [org.elasticsearch.common.geo.GeoPoint]."`  
I tried multiple things with my `i`...

Do anyone of you see what I'm doing wrong?

Thank you!

I've found a few things from here [https://github.com/elastic/elasticsearch/issues/25796](https://github.com/elastic/elasticsearch/issues/25796)

And as the only suggestion is labelled for v7.0, I used the last answer loop, which calculates the distance without the arcDistance function...
