Importing a character from blender comes with a Huge Bounding Box

Hi, I modeled and rigged a character that I'm importing as a glb file into Aero.
I works all right, but I have to change the pivot to Origin because when it's imported

it comes with a gigantic bounding box and the pivot is far away.
I thought that maybe I had a loose part or an extra element, so I tested sending just the meshes without

the armature and it imported well.
I also re-imported that glb into blender and it comes with the right pivot and bounding box.
Any idea?
