[Maya-Python] Parent Constraint Issue when removing constraint

[Virbhadra Gupta]

Hello, i am trying to remove parent constraint using parentConstraint
command.

but constraint created by skipping any Tran or Rot attrs
cmds.parentConstraint(obj1, obj2, rm=True) won't work why ??

am i doing something wrong ??

here is sample code and error:

# Creating two objects
box1 = cmds.polyCube(n="box_01")[0]
box2 = cmds.polyCube(n="box_02")[0]

# Creating parent Constraint only for Translation
cmds.parentConstraint(box1, box2, mo=True, sr=["x","y","z"])

# checking if "box_02" have parent constrint
consObj = cmds.parentConstraint(box1, q=True, tl=True)

# removing constraint
cmds.parentConstraint(consObj[0], box2, rm=True)
