Hi,

I am using ElasticSearch and Kibana 7x version, I am trying to concatenate two fields values.

Before I write actual concatenation painless script, I tried accessing field values from scripted field.

when I run the query `doc['destination.domain'].value` it is not giving any values instead it is showing `[]`  
But the actual values of `destination.domain` field is something like `test.mydomain.com`.

What could be the issue causing this error?

Somehow it is showing the null value `[]` in preview results. But when I create the field and access the value from discover section, the value is coming properly. The script I wrote like

```auto
if (doc['destination.domain'].size()!=0 && doc['file.val'].size()!=0){ 
    return doc['destination.domain'].value + '' + doc['file.val''].value
}

```

If it shows `[]` in the preview results is due to there being no documents in the last 10 that match your script, for example those with `destination.domain` being empty.
