Hello guys, I am trying to rig the fingers of my character but i get this error line on the second run. Kindly check if you would be able to help find the error(could it be the naming convention? Kindly see the screenshot attached):

import maya.cmds as cmds

def kl_fkChain(lookFor='FNG'):
root = cmds.ls(sl=1)
child = cmds.listRelatives(root, typ='joint', ad=1)
child.reverse()
allJnts = root + child
print allJnts

for j in allJnts:
if not 'End' in j:
grpN = j.replace('_JNT', 'Orient_GRP')
grpM = j.replace('_JNT', 'Modify_GRP')
ctl = j.replace('_JNT', '_CTRL')
cmds.circle(n=ctl)
cmds.group(n=grpN, em=1)
cmds.group(n=grpM, em=1)
cmds.parent(ctl, grpM)
cmds.parent(grpM, grpN)

tmpCons = cmds.parentConstraint(j, grpN, mo=0)
cmds.delete(tmpCons)

cmds.connectAttr("%s.rotate" % ctl, "%s.rotate" % j)

rel = cmds.listRelatives(j, p=1)
if rel:
if lookFor in rel[0]:
rel = rel[0].replace('_JNT', '_CTRL')
cmds.parent(grpN, rel)

kl_fkChain(lookFor='FNG')

Might I suggest some additional print statements.  They are a great way to debug.  I would print when you create your "_CTL" node so you know what you've created.  Then another print of "rel" so you know what you are trying to parent to.  You might want to add a conditional to check if "rel" exists.  And then give yourself another print statement to inform you if it does not.  This way, your code won't error and you get useful information.

Thanks for the reply. I'm pretty new to python in Maya and do not know how to really workaround it yet. Just following tutorials.

Figured it out. It was my naming of joints. I added the 'FGN' to the parent node of my joints😅. This was what caused the error and it's working fine now after removing it. Cheers😁

and what is FGN?  can you post the exact code to fix this?  as Im having the same issue

I think that was a typo.  I think he meant "FNG" for "finger".
