Switched to 4.3 from 4.2 and now punch is broken

4.3

Question

So when i switched from 4.2 my punch broke and i cant figure out why

My code had a code to do the damage on area 2D

extends Area2D

@export var damage : int = 1 


func _on_body_entered(body):
	for child in body.get_children():
		if child is Damageable: 
			child.hit(damage)

and a player body 2d that is supposed to receive the damage from the punch collision but it does nothing

extends Node

class_name Damageable

@export var health : float = 1:
	get:
		return health
	set(value):
		SignalBus.emit_signal("on_health_changed", get_parent(), value - health)
		health = value

func hit(damage: int):
	health -= damage
	
	if(health <= 0):
		get_parent().queue_free()

And i have tried with the layers but the character works with another collision in the same scene on the same layer but the enemy does not get affected by the punch

The code seems fine. Are the collision layer and mask set up correctly?
You could also adapt the 4.x way of emitting signals:

SignalBus.on_health_changed.emit(get_parent(), value-health)

[FreakyGoose]

You may need to reconnect the signals from the signal tab.

I checked and the layer and mask are set up and ill be sure to try the way you suggested of emitting signals
