JSON Shapefile

[Anonymous User]

Hi all,

I am trying to write JSON to a shapefile from my JS app.  I am using two third party libs here.

1. Terraformer to parse JSON to GeoJSON

2. GitHub - mapbox/shp-write: create and write to shapefiles in pure javascript

DrawToolbar.on("draw-end", function(e) {
            DrawToolbar.deactivate();
            var symbol = new SimpleFillSymbol(
              "solid", 
              new SimpleLineSymbol("dash", new Color([255,0,0]), 2), 
              new Color([255,255,0,0.25])
            );
            var graphic = new Graphic(e.geometry, symbol);
            var json = graphic.toJson();
            // parse an ArcGIS Geometry to GeoJSON
            var Areas = Terraformer.ArcGIS.parse(json);
            console.log((Areas));
            shpwrite.download({
            type: 'FeatureCollection',
            features: Areas
            }, options);
            
            map.graphics.add(graphic);
        });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I get this error: 

Any idea?
