Hi, i imported a csv file with a date column (Format example: '2019-05-01') and Kibana does not recognize it and read it like string.  
I tried to transform it with a scripted field:

> doc['Fecha'].value

I put date in the type and save successfully, but when i try to make a line chart, i got this error when a put in the X axis the new date created:

Can you share the mappings for the Fecha field? If it's a string and we want the scripted field to be a date we'll have to coerce it. Ideally the csv import is mapping the field as a date, but if not something like:

```auto
 new SimpleDateFormat('yyy-MMM-dd').parse(doc['Fecha'].value).getTime();

```
