Trouble with GameCamera

My camera had been working fine, but I had an issue with draw order. So it solve the problems I was having, I added CanvasLayers (Background, Foreground, and UI) and organized all of my scenes accordingly. I left the Camera where it was in the main parent tree. The camera is controlled via a script.

here is the code:

extends Camera2D

@export var backgroundColor :Color
@export var shakeNoise : FastNoiseLite

var targetPosition = Vector2.ZERO
var xNoiseSampleVector = Vector2.RIGHT
var yNoiseSampleVector = Vector2.DOWN
var xNoiseSamplePosition = Vector2.ZERO
var yNoiseSamplePosition = Vector2.ZERO
var noiseSampleTravelRate = 300
var maxShakeOffeset = 7
var currentShakePercentage = 0
var shakeDecay = 3

# Called when the node enters the scene tree for the first time.
func _ready():

# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta):
	global_position = lerp(global_position, targetPosition, pow(2, -15 * delta))
	if currentShakePercentage > 0:
		xNoiseSamplePosition += xNoiseSampleVector * noiseSampleTravelRate * delta
		yNoiseSamplePosition += yNoiseSampleVector * noiseSampleTravelRate * delta
		var xSample = shakeNoise.get_noise_2d(xNoiseSamplePosition.x, xNoiseSamplePosition.y)
		var ySample = shakeNoise.get_noise_2d(yNoiseSamplePosition.x, yNoiseSamplePosition.y)
		var calculatedOffset = Vector2(xSample, ySample) * maxShakeOffeset * pow(currentShakePercentage,2)
		offset = calculatedOffset
		currentShakePercentage = clamp(currentShakePercentage - shakeDecay * delta, 0, 1)

func acquire_target_position():
	var acquired = get_target_position_from_node("player")
	if !acquired:

func get_target_position_from_node(groupName):
	var nodes = get_tree().get_nodes_in_group(groupName)
	for node in nodes:
		targetPosition = node.global_position
		return true
	return false

func apply_shake(percentage):
	currentShakePercentage = clamp(currentShakePercentage + percentage, 0, 1)

I did a print(global_position) in the func _process(delta), and the value changes as my character is moved. But for whatever reason the camera just sits at -180, -144, which is the center of a blue box in the editor. I can only assume the camera isn’t moving because of some relative position setting and it broke because I moved everything into CanvasLayers. I really don’t want to undo my CanvasLayers.

I found the problem. When I created the CanvasLayers, I did not know that there is a setting called “Follow Viewport” for it. For my background and foreground, I turned this on and it fixed my issue.
