What is the issue here - Enchantments

{
    "anvil_cost": 0,
    "description": "",
    "max_cost": {"base": 0,"per_level_above_first": 0},
    "min_cost": {"base": 0,"per_level_above_first": 0},
    "max_level": 1,
    "slots": ["hand"],
    "supported_items": "#enchantable/weapon",
    "weight": 1,

    
    "effects": {
       "damage": [
        {
            "effect": {"type": "multiply", "factor": 1.115 } , "requirements": [{"condition": "entity_properties", "entity": "this", "predicate": {"slots": {"weapon.mainhand": {"predicates": {"custom_data": {"Lethal": 1}}}}}}]
        }
       ]
    }
}

This works without the conditions, though the condition works in a predicate so Idk what might be wrong
