I am getting one weired error.

I have field called no\_of\_scanned value which is String in Kibana

The data look like 1234 4567 etc

I cant do some aggregation so trying to convert this into int/double . SO I created a scripted field and select the type as number .

Here is my painless script :

```auto
return Double.parseDouble(doc['no_of_scanned'].value)

```

I am expecting an double to be returned .

But the result in console is looking like below.

```auto
[
{
  _id:"some randomid of elastic",
   zzz : [1898]

},
..
..
]

zzz is my scripted field. 

```

Please let me know why zzz value is surrounded by . I want just number to be returned.
