Cropped 3d tiled model using cesium ion tiler pipeline issue

Hi, I’ve got some issue trying to upload my 3D tiled model through cesium ion. My model is somehow got cropped after uploaded.

I’ve checked in my local viewer (agisoft viewer) and there seems to be no issue. I’ve uploaded several models, and never got this kind of issue before.
