Looking at predicate not working (1.20.1)

i literally do not understand why this isnt working. i even used the predicate generator
  "condition": "minecraft:entity_properties",
  "entity": "this",
  "predicate": {
    "type_specific": {
      "type": "minecraft:player",
      "looking_at": {
        "type": "minecraft:pig"
      }
    }
  }
}```
