Short description of error
bpy.ops.armature.rigify_upgrade_layers() gives an error when trying to update a custom metarig.
It can even be as simple as just one bone with the "basic.super_copy" property.

Exact steps for others to reproduce the error
Create a simple metarig in blender 3.6.7 with just one bone, assign a "basic.super_copy" property to it and hit generate. Save file.
Open said file in blender 4.0.2 and try to press the "Upgrade metarig" on the metarig to use the new bone layers and you should get this error:

Python: Traceback (most recent call last): File "C:\Program Files\Blender Foundation\Blender 4.0\4.0\scripts\addons\rigify\ui.py", line 1081, in execute upgrade_metarig_layers(verify_armature_obj(context.active_object)) File "C:\Program Files\Blender Foundation\Blender 4.0\4.0\scripts\addons\rigify\utils\rig.py", line 209, in upgrade_metarig_layers names = resolve_layer_names(layers) File "C:\Program Files\Blender Foundation\Blender 4.0\4.0\scripts\addons\rigify\utils\rig.py", line 141, in resolve_layer_names if name := layer.get("name").strip(): AttributeError: 'NoneType' object has no attribute 'strip'

I have included a test file created in blender 3.6.7 for you tu try
