Error in render : Fx error when rendering it as a module

[abrhambas01]

I'm using vue.js in this app and I tried importing the js file as an es6 module something like this:

import fx from './money.js';
export default {
// lots of code here..
}

I also tried including it as a JS module something like this

<script src="js/money.js"></script>

still i get an

[Vue warn]: Error in render: "fx error"
found in PlegeOffer.vue

and

fx error or something like that
