Some Glb file will not load

[lagence3d]

Hello,

Some simple Glb files will no load, there are opened correctly by GlfViewer and Windows 3D Viewer.
Here is the error in the console :

RayTracingRenderer.js:446 Uncaught ERROR: 0:7: 'NUM_MATERIALS' : undeclared identifier
ERROR: 0:7: '' : array size must be a constant integer expression
ERROR: 0:8: 'NUM_MATERIALS' : undeclared identifier
ERROR: 0:8: '' : array size must be a constant integer expression

Here is an example of a simple wall in Glb format.
