Short description of error

I figured the Upgrade Metarig option in Blender 4 for rigs made in 3.x version are only working if they were created using pre-made "Human (Meta-Rig)". But you got an error if you were building your rig out of single samples. It could be just a single sample, like one Leg - it makes that error to appear when one is trying to upgrade that rig in Blender 4.

Exact steps for others to reproduce the error

Open blender 3.x
add an armature/single bone
click the bone, turn the edit mode, delete the bone
in a Data/Rigify/Samples find limbs.leg - press Add sample
press Generate Rig
save file
open it in blender 4
choose the metarig in the viewport
Press Data/Rigify/ Upgrade Metarig
ERROR

I have figured you can workaround this issue by deleting rigify_layers from Custom properties, but then you gotta manually set up all the new bone groups which is pretty tedious
