How to debug Babylon Blender scene export/import?

I am using Blender 2.8 and the latest Babylonblender exporter. I have exported a scene and have a .babylon , .babylon.manifest and .log file. The log file dosen’t show any errors and the data in the .babylon file seems to represent everything in the scene.

I am trying to render the scene using the BABYLON.SceneLoader

    BABYLON.SceneLoader.Load("", "assets/man.babylon", engine, function (scene) {
      engine.runRenderLoop(function() {

      window.addEventListener("resize", function () {

This does not render anything and no errors are thrown either.

The forum won’t let me upload files as a new user. You can find a zip of the .blend file and the .babylon files at : Dropbox - - Simplify your life

If you’re looking to actually debug the code you can get VS code, with the chrome debugger extension and hit: http://localhost:8888 or whatever you prefer.
