Describe the bug
I'm going through some of the older Blender splash screen files and testing whether they export cleanly as glTF by now.

To Reproduce
Steps to reproduce the behavior:

  1. Download https://cloud.blender.org/p/gallery/5d2607ee6b3001d49bab798a
  2. Open with latest Blender (e.g. 4.3 alpha)
  3. Export as GLB
  4. See error

Expected behavior
Export works, even when not all scene content is exported

Confirmed.
Root cause is a lattice with armature.
We need to exclude lattice , this is not an object that we can/want to export
