Trying to add an interaction to terrain but it's causing a route failure

I couldn't change the puddle spawning but I think it's okay the way it is, it doesn't bother me that much.

I tried to make a script based off the one from this thread by replacing the names and interaction hash ids to inject the interactions to object_terrain but how should I add it to the package? Do I save it as .py and put it in the Mods folder or do I need a .pyo file too? If a .pyo is needed, how does that file need to be? This is my first time scripting so I'm not really sure.

Script:

import services
import injector
import sims4.resources
from sims4.tuning.instance_manager import InstanceManager
from sims4.resources import Types

TS40_PeeHere_Interactions_ObjectTerrain_sa_instance_ids = (15295192161465113131, 6192637829597138744,)
TS40_PeeHere_Interactions_ObjectTerrain_object_ids = (14982,)

@injector.inject_to(InstanceManager, 'load_data_into_class_instances')
def add_superaffordances(original, self):
    original(self)

    if self.TYPE == Types.OBJECT:
        affordance_manager = services.affordance_manager()
        sa_list = []
        for sa_id in TS40_PeeHere_Interactions_ObjectTerrain_sa_instance_ids:
            key = sims4.resources.get_resource_key(sa_id, Types.INTERACTION)
            sa_tuning = affordance_manager.get(key)
            if not sa_tuning is None:
                sa_list.append(sa_tuning)
        sa_tuple = tuple(sa_list)

        for obj_id in TS40_PeeHere_Interactions_ObjectTerrain_object_ids:
            key = sims4.resources.get_resource_key(obj_id, Types.OBJECT)
            obj_tuning = self._tuned_classes.get(key)
            if not obj_tuning is None:
                obj_tuning._super_affordances = obj_tuning._super_affordances + sa_tuple
