Godot queue_free() instancing problem

So I’m creating a simple 2D breakout game and I have instanced the bricks in code. I created somewhat of a grid of bricks but the problem is that when the ball hits any one of the bricks then all the bricks are gone/deleted.

func spawn_bricks(row,column):
var pos_x = 64
var pos_y = 0
#column
for i in range(row):
	pos_y += 32
	pos_x = 64
	#row
	for j in range(column):
		brick = BRICK_SCENE.instance()
		brick.add_to_group("Bricks")
		brick.position = Vector2(pos_x, pos_y)
		pos_x += 64
		add_child(brick)

#Rigidbody2D Ball uses signal body_entered and deletes brick  
func _on_Ball_body_entered(body):
	if body.is_in_group("Bricks"):
		call_deferred("free")

The bricks are ordered in rows and columns so ‘spawn_bricks(3,5)’ would spawn 3 rows of 5 bricks. Is there any way where if the ball collided with one brick then that brick is deleted and not the whole grid.

Your code is deleting the brick manager, not the bricks. Try changing the code to

func _on_Ball_body_entered(body):
    if body.is_in_group("Bricks"):
        body.call_deferred("free")

You need to get the individual brick to run the free code.
