I have an FBX file that I took from unity. It has a couple of keyframes on it. When I try to import it in blender 4.1, it shows me the following error

Python: Traceback (most recent call last):

KeyError: None

Can someone explain why is it happening and how can I solve it?

**System Information**
Operating system: Windows 11
Graphics card: Nvidia GeForce GTX 1060 3GB

**Blender Version**
Broken: (example: 2.80, edbf15d3c044, master, 2018-11-28, as found on the splash screen)
Worked: (newest version of Blender that worked as expected)

**Short description of error**
Unable to import fbx correctly

**Exact steps for others to reproduce the error**
Based on the default startup or an attached .blend file (as simple as possible).

Similar error to #104885 but I'm unsure if they're the same issue since this one is complaining about KeyError: None.

I think the issue here is that there is a bone (LimbNode) called root at the top of the hierarchy which then has an 'armature' (Root) called DUCK_ parented to it, and the FBX importer doesn't like that.

If I manually edit the attached FBX and make root the Root and make DUCK_ a LimbNode then the import succeeds, but decides to make root the Armature Object itself.
