Use file.js in karate dsl

Question

I am trying to call a function that I have defined in a js file in karate dls

This is the file "utils.js"

function Encriptar(text,key) {
    var CryptoJS = require('crypto-js');
    var encoded = CryptoJS.AES.encrypt(arguments[0],arguments[1]).toString();
    return encoded;
}

module.exports = Encriptar;

I think that's how it would be used from a feuture in karate "test.feature"

Feature: test javascript
Scenario: test javascript
* def jsFunction = call read('utils.js')
* def encriptar = jsFunction.Encriptar("text","key");
* print encriptar

When running the test it gives me the following error:

>>> failed features:
>>>> js failed:
01: read('utils.js')
<<<<

04:     return encoded;
05: }
