hi all and sorry for my poor english .  
I have an index with this mapping

```
"mappings":{

    "properties":{

        "_class":{

        "type": "text",

        "fields":{"keyword":{"type": "keyword", "ignore_above": 256 }}

        },

        "my":{

           "type": "keyword" 

        },

        "notifications":{

            "type": "nested",

            "properties":{

                "detail":{"type": "keyword"},

                "identifier":{"type": "keyword"},

                "modelType":{"type": "keyword"},

                "notificationDate":{ "type": "long" } 

             }

    }

}

```

I'm creating a script on notificatioDate fields.  
But when I do doc['notifications.notificationDate'].value , kibana says me 'Script not valid' with no reason specified

Consider that it 's searchable and aggragatable.

Here's a Stack Overflow post on using `_source` instead of `doc` in the script: [elasticsearch - How to access nested property at script\_fields on elastic 5.x - Stack Overflow](https://stackoverflow.com/questions/41275228/how-to-access-nested-property-at-script-fields-on-elastic-5-x)
