I'm trying to update this add-on to Blender 2.8, I've update some of the code, but I got stuck on some errors happening.
Traceback (most recent call last): File "/home/lucas/Desktop/Prêt-à-Template/01_3d/maternity_10.blend/ApplyModifierForObjectWithShapeKeys.py", line 107, in execute File "/home/lucas/Desktop/Prêt-à-Template/01_3d/maternity_10.blend/ApplyModifierForObjectWithShapeKeys.py", line 52, in applyModifierForObjectWithShapeKeys File "/home/lucas/Softwares/blender-2.81/2.81/scripts/modules/bpy/ops.py", line 201, in call ret = op_call(self.idname_py(), None, kw) TypeError: Converting py args to operator properties: : keyword "constraint_orientation" unrecognized

# Algorithm:
# - Duplicate active object as many times as the number of shape keys
# - For each copy remove all shape keys except one
# - Removing last shape does not change geometry data of object
# - Apply modifier for each copy
# - Join objects as shapes and restore shape keys names
# - Delete all duplicated object except one
# - Delete old object
# - Restore name of object and object data
