javascript api 3.13 geometryEngine.geodesicBuffer error

Im trying to use the new geometryEngine.geodesicBuffer. when passing in my polygon geometry, the api is throwing the following error. (Uncaught TypeError: Cannot read property 'dd' of null) geomtryEngine.js: 519

I believe this is a bug in the new client side geometry engine.

I'm using Web Mercator projection (wkid 102100).

var SelectGraphicsLayer = map.getLayer("SelectGraphicsLayer");

var _geometry;

var _geometries = [];

for (var i = 0; i < SelectGraphicsLayer.graphics.length; i++) {

_geometries.push(SelectGraphicsLayer.graphics.geometry);

}

if (_geometries.length > 1) {

_geometry = GeometryEngine.union(_geometries);

}

else {

_geometry = _geometries[0];

}

//var buffer = GeometryEngine.buffer(_geometry, 330, Units.FEET, true); //THIS ONE WORKS

var buffer = GeometryEngine.geodesicBuffer(_geometry, 330, Units.FEET, true); // THIS ONE DOES NOT

The geodesicBuffer takes a number for the units. Try specify 9002 as the third argument. See https://developers.arcgis.com/javascript/jsapi/esri.geometry.geometryengine-amd.html#geodesicbuffer which has a link to esriSRUnitType Constants.

While not technically a bug, this syntax is likely to change for the next version.
