Checking if the attacked entity has a tag

Hey, I wanted to check if the entity the player has attacked has the hostile_entity tag. But it activates for every entity: { "criteria": { "requirement": { "trigger": "minecraft:player_hurt_entity", "conditions": { "damage": { "type": { "source_entity": {} } }, "damaged": { "tag": "hostile_entity" } } } }, "rewards": { "function": "immersive_combat:start_combat" } } What is wrong here?
