glb has validation errors see https://github.khronos.org/glTF-Validator/

[emackey]

Yes. In particular, on line 80, the validator calls out that a material with a texturemap is being used on a mesh with no texture coordinates. This is likely the cause of the Cesium error. You can't have a texture without supplying texture coordinates.
