TypeError while using gltfjsx to an animated model: Cannot read properties of null (reading 'array')

Hello, I am struggling to an error while using the gltfjsx command-line tool to turn an animated model into a TSX component.
My model is rigged using the rigify addon in blender 4.1 like the following:


Then I exported my model to the glTF 2.0 format with the following export configuration:

When I check it first to the gltf viewer and it render correctly with the skeleton and the animation.

So I try to use the gltfjsx command-line tool to implement into my code with the following command:

npx gltfjsx ./public/3d/avatar/mii_avatar.gltf --transform --types

But I got this error as a result:

prune: Removed types… Accessor (16)
prune: Removed types… Material (10)
prune: Removed types… Accessor (158)
instance: Instancing is not currently supported for animated models.
prune: No unused properties found.

I don’t know what I did wrong in my model maybe using rigify for my model is not the best option to export it on the web. 🤔
And It only happen with this file, if I use it with others gltf model from blender then it's work like a charm and generate the .glb and the .tsx component.
You can find enclosed a zip file containing my avatar model with his armature and his 3 animations.
Any help would be greatly appreciated.
Thank you in advance.
