colorfactor_path: list index out of range KHR_animation_pointer

Describe the bug
Hello. I cannot export the attached asset when Animation Pointer is toggled.

To Reproduce
Steps to reproduce the behavior:

1. Open the attached .blend file
2. Attempt to export it.
3. See the error message.

Expected behavior
The asset should be exported.

.blend file/ .gltf (mandatory)

Additional Context
I'm not sure for what reason a Mix Node is connected to Specular Tint. This node setup was generated by an older version of Blender (I don't know which one). It might be a bug that has already been fixed.

Version

• OS: Linux
• Blender Version 4.2

Hello,

I can confirm
Investigation in progress

PS: The Mix Node is created when you open an older (than 4.0) blend file.
For 4.0 release, a new Principled BSDF node was introduced, and for compatibility with older files, some node tree are created to keep shader as soon as possible, visually.
