I'm trying to extend the sale .ProductConfiguratorMixin JS module, at /sale/static/src/js/product_configurator_mixin.js; I've tried via the two ways provided in the answers linked below to no avail.

Below is the code I've got right now; it's not executing, since the print doesn't appear in the console nor the extended function in a console.trace() i called.

odoo.define('mymodule.ProductConfiguratorMixin', function (require) {
'use strict';

var Widget = require('web.Widget');
var ProductConfiguratorMixin = require('sale.ProductConfiguratorMixin');

return Widget.include(ProductConfiguratorMixin, {
    _getCombinationInfo: function (ev) {
    console.log('THIS SHOULD GET PRINTED');
     the rest of the function, unaltered 
    },
});

});
