Hi, i want to create a custom field in kibana, i tried to follow the instructions at

> **[Writing Custom Field Formatters for Kibana
	  	 | Elastic](https://www.elastic.co/blog/kibana-custom-field-formatters)**
>
> Kibana 4.1 introduced a new feature called field formatters, giving us the ability to visually convert fields on the fly.  Field formatters provide a great way to display data in a different way&...

  
but when i start kiban launching bin/kibana --dev i get this error:

```
    SyntaxError: Unexpected token ILLEGAL

```

How can i solve it?

Thanks in advance.

my custom field should show a player that reproduce a mp3. The field should take the filename from the field and load the mp3 from a url completed by filename.  
What i don't undestand is 2 things:

1. i cannot start kibana dev environment because of the problems showed above altough i followed the guide step by step and i have installed all the libraries required
2. Even if i can run tge dev environment and create a new type in /src/ui/public/stringify (or /src/kibana/components/stringify), how can i port this custom field in production?  
thanks in advance
