   console.log("=== completed ===");

   console.log(result);

 }

```

}

catch (err) {

```
 console.log(err);

```

}

}

return 'Successfully processed: ${event.Records.length} records.';

};

I am using above node js code for lambda function.  
I can able to convert the unix timestamp to date. But it is still converting as a string and not allowing me to use data range or date histogram options in kibana.

Any help can be appreciated.

What is your [mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/date.html) for that field in that index? It needs to be a `date` if you want to perform functions in Kibana as a date.

I am not sure how to give format as date in my above code.

But i tried try{

```
      date = new Date(record.dynamodb.NewImage?.timestampResult?.N * 1000).toISOString()

    }

  catch(e)

  {

      date = record.dynamodb.NewImage?.timestampResult?.N

  }

```

and in body i gave .D as well for respective field.

And even if i pass a number it is somehow converting as a string in kibana.
