Python error when using Dupl. Sym

[JKG2]

Hi all, new mGear user here with previous moderate rigging experience.

I’m rigging with the sample quad rig, but when I try to symdupe the back leg, Im getting a Python error (disclosure: IANAP)

Error: RuntimeError: file C:\Program Files\Autodesk\Maya2022\Python37\lib\site-packages\pymel\internal\pmcmds.py line 217: setAttr: Error reading data element number 1:

All relevant elements are set as “Left”, no centers found.
Here’s a heirachy screenshot, any help is much appreciated, thanks.

You can delete the ‘legBack’ module and load the same ‘leg_3jnt_01’ module. Then, try duplicating the module symmetrically by selecting its root. Let’s see how it goes.
