Error while importing FBX

[Zumar_Ahmad]

Hi, I have been trying to import an FBX into blender 3.6. When I import it gives the following error

Python: Traceback (most recent call last):
File “C:\Program Files\Blender Foundation\Blender 3.6\3.6\scripts\addons\io_scene_fbx_init_.py”, line 207, in execute
if import_fbx.load(self, context, filepath=path, **keywords) == {‘FINISHED’}:

(mmat, amat) = mesh.armature_setup[self]
KeyError: None

I am not into coding that much so doesn’t know the reason for it. Can anyone of you help me out sorting this issue.
Thanks

The most important message from the error log is the last one:

(mmat, amat) = mesh.armature_setup[self]
KeyError: None

Looks as if something is going wrong with the armatures in your FBX and the Blender importer. I am not an expert on FBX nor on armatures. But it looks as if there are already a few tickets on Blender side that mention some limitations:

Fbx Import Error in Blender 3.1.2

FBX Export/Import armature child of another armature causes a bug

[FBX Import] Wrong scale on imported objects - General multi-level parenting...

And there is also some discussion ongoing in here on FBX and Blender im- and export. Although it is mostly for export, maybe there are some helping comments?

FBX / glTF export - how to NOT export Armature in the hierarchy ?!

I used to use a trick that would prevent Blender to export Armature in the skeletal hierarchy when exporting to FBX. This trick has been lost, unfortunately. How can I modify FBX exporter to NOT export Armature as root component? (root should be root bone, not Armature with root bone being its first child) glTF2 exporter is even worse, because it also inserts skinned mesh into hierarchy of the skeleton. Is there a way to NOT do that and have clean skeleton hierarchy in the exported glTF2 file …

I did go through all of the links you mentioned, found a couple of addons but still the issue is not resolved. The addons work mostly for the export process. I am unable to get it imported in the first place.
