Some models contain an empty optional array

@lasalvavida can you make this change?

Thanks @peteroupc @lasalvavida!

This issue originally dealt with the animation array, but in fact this points to a broader issue: some models contain empty arrays where they're optional in the schema. For example, this broader issue persists in the AnimatedCube model with the children property, and possibly in other models with that or other properties.

@McNopper, for your reference. It sounds like this may be an issue in your exporter

[UX3D-nopper]

These models were exported directly from my Vulkan examples. I will check this. Thx.

In the Blender glTF 2.0 exporter, this should not appear.

Just checked, it is my "Vulkan" to glTF 2.0 exporter. Currently revisiting the whole code anyway.

The Blender glTF 2.0 exporter is doing it correct.
