Version 2.17 - WGS is not defined

Question

Updating from v2.16 to v2.17, I have downloaded the viewer and model files to use them locally. If I use the local version, I get an error

Uncaught ReferenceError: WGS is not defined
    at new f (viewer3D.min.js?v=v2.17:10)
    at a.e.loadModel (viewer3D.min.js?v=v2.17:20)
    at a.loadModel (viewer3D.min.js?v=v2.17:22)
    at Object.initialize (viewer-embed.js:125)
    at HTMLDocument.initialize (model:198)
f @ viewer3D.min.js?v=v2.17:10

a.loadModel @ viewer3D.min.js?v=v2.17:22
initialize @ viewer-embed.js:125
initialize @ model:198

It appears that WGS.min.js is no longer loading before this line is executed? Current fix is to include it explicitly:

<script src="/Scripts/viewers/three.min.js?v=v2.17"></script>
<script src="/Scripts/viewers/WGS.min.js?v=v2.17"></script>
<script src="/Scripts/viewers/viewer3D.min.js?v=v2.17"></script>

Edit: Debugged through viewer3d.js to track the loading of WGS.js, and it appears that my call to loadModel() with the url of the local model is happening too soon, and before WGS.js has finished loading.

Not sure why I had the loadModel() call after Autodesk.Viewing.Initializer() instead of in the callback to it, but moved it into the callback and it works. Now not sure how it ever worked with previous versions, but working now.

Answer 1

Do you have local version of these files? The viewer3d.js will load additional files, including wgs.js and lmvworker.js

Just tried the following and it's working fine (from here):
