Thanks for the file. I tried to export your model in FBX format but it imports fine without any error (tested on 3.0.0 and current master)
Can you please share export settings? Or simply provide .fbx file where importing fails?

@iss, found this issue was reported before: #82246 (I want to import FBX with blend shape from Maya and export it as glb.)
Would be safe to merge them.

Will merge #82246 here since this is confirmed and there is no data from report author. Thanks for finding duplicate.

Good Morning.
In this case, i used the bridge from Daz Studio. The animation is working but i lost the controlers and the bones. Look that the "Report Error" mentioned the Python again. All this troubles started whem i change to Blender 3.0.

Hi @MarcM, looks like the Daz bridge needs an update for 3.0.
There was a breaking change in regards to custom_shape_scale:
