In my kibana dashboard version 6.6.0

 ![1kp](https://us1.discourse-cdn.com/elastic/original/3X/6/f/6fb8e1cd153f4dc420835ebf6be77c7bef10dbce.png)

Now i want to create a new field using script field called "firstname"

**my script field:**

> doc["user.first].value[1]

**getting shards are failed**

also tried  
doc['user.first'][0] ,  
params['\_source']['user.first'][0] but same error

reference used:

> **[Nested field type | Elasticsearch Guide \[8.11\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/nested.html)**

1. here can we treat user.first behaves like array for each document ?

2. how can i access array of objects in the documents of an index ?

3. In saved search its showing objects in arrays are not well suported,how to resolve this issue ?

If you'd just like to have a scripted field that gets only the first first name for each document, you can do so like this:

```auto
params._source.user[0].first

```

If you'd like to have a scripted field that gets all of the first names for each user in each document, you can do something like this:

```auto
def firstnames = [];
for (item in params._source.user) {
  firstnames.add(item.first);
}
return firstnames;

```

In general, having objects in arrays is not something that plays well with Kibana. If you can figure out a way to structure your data so that each document has a "group", "first", and "last" instead of an array of objects, it will be easier to use Kibana to visualize your data.

You can see an example here: [Sorting comblex Array elements with Painless script](https://discuss.elastic.co/t/sorting-comblex-array-elements-with-painless-script/118472)
