When I execute this command node obj2gltf/bin/obj2gltf.js -i model.obj -o box.gltf
An error like this occurs： Normal index 12868 is out of bounds

Are you using Vectorworks? I saw a similar bug report in assimp: assimp/assimp#2428

It looks like assimp decided to coerce NaNs to 0s: assimp/assimp#2429

I'm also facing the same with but with a bit different message 'Normal index 47 is out of bounds'
