I have the following code and want to add a driver to the rest length of the stretch to constraint (bone constraint), but the console says that the property path is invalid. What am I doing wrong?

armature = Name of my armature
str(GrpName)+"_bone" = Name of the armatures bone

BaseLenghtDrv = bpy.data.objects[armature].pose.bones[str(GrpName)+"_bone"].driver_add('pose.bones["'+str(GrpName)+'_bone"].constraints["Stretch To"].rest_length').driver

The code before the driver_add parentheses is definatelydefinitely correct, I tested it with the rotation quaternion of the bone and it worked. But it doesn't work with the bone constraint.

PYTHON Bone Constraints and Driver Creating a driver on a constraint with python?

Hei Guys,

i have a short question. I have the following code and want to add a driver to the rest lenghtlength of the stretch to constraint  (Bone Constraintbone constraint). But everytime, but the console says that the Property Pathproperty path is invalid. What am iI doing wrong  ?

Variables armature = Name of my armature str(GrpName)+"_bone" = Name of the armatures bone

armature = Name of my armature
str(GrpName)+"_bone" = Name of the armatures bone

BaseLenghtDrv = bpy.data.objects[armature].pose.bones[str(GrpName)+"_bone"].driver_add('pose.bones["'+str(GrpName)+'_bone"].constraints["Stretch To"].rest_length').driver

PS: The Codecode before the driver_adddriver_add parentheses is definately correct i, I tested it with the rotation quaternion of the bone and it worked but not. But it doesn't work with the bone constraint.

I hope someone can give me an advice :)
