Uncaught TypeError: Cannot read property 'lng' of undefined, while using example from documentation.

I am using the following, from the example, and get an error.

        var pointList = [new L.LatLng(20.00, 140.0), L.LatLng(50.00, -120.0), L.LatLng(70.50, 170.0)];

        //Create and display a wrapping polygon.
        new lw.Polygon(pointList, {
            color: 'red',
            weight: 3,
            opacity: 0.5,
            smoothFactor: 1,
            noWrap:true
        }).addTo(map);

error:

I should note I am using Meteor and running the following code to import the JS file:

import * as lw from '../../../client/js/leaflet.antimeridian-src.js';
