Godot data type error

Hi friends,
In the Load function, I’m getting these errors for stars and hiPoints:

“Invalid assignment of property or key ‘stars’ with value of type ‘Array’ on a base object of type ‘Resource (Player_Data)’.”

“Invalid assignment of property or key ‘hiPoints’ with value of type ‘Array’ on a base object of type ‘Resource (Player_Data)’.”

However, in my Player_Data class, both of these are already defined as arrays. I haven’t been able to solve the issue. I’ll drop the code below.

Player Data:

extends Resource
class_name Player_Data

  # oyuncunun seviye ile ilgili bilgiler
  var max_level: int = 0
  var last_level: int = 0

  # oyuncunun başarımları
  var stars: Array[int] = []
  var hiPoints: Array[int] = []

 # oyuncunun varlıkları
  var gold: int = 0

Load function code of Save’s Node:

func load_data():
	
	if FileAccess.file_exists(dir+path):
		var file = FileAccess.open_encrypted_with_pass(dir + path, FileAccess.READ, key)
		if file == null:
			print("Dosyaya erişilemedi: ", FileAccess.get_open_error())
			return
		var content = file.get_as_text()
		file.close()
		
		var data = JSON.parse_string(content)
		if data == null:
			return
		
		
		var player = data["player_data"]
		
		Ref.player_data = Player_Data.new()
		
               # seviye bilgileri
		Ref.player_data.last_level = 0 if !player.has("last_level") else player["last_level"]
		Ref.player_data.max_level = 0 if !player.has("max_level") else player["max_level"]
		
              # oyuncu başarımları
		Ref.player_data.stars = [] if !player.has("stars") else player["stars"]
		Ref.player_data.hiPoints = [] if !player.has("hiPoints") else player["hiPoints"]
		
              # oyuncu varlıklıkları
		Ref.player_data.gold =  0 if !player.has("gold") else player["gold"]
		
			
			
	else:
		print("Dosya mevcut değil: ", FileAccess.get_open_error()) 
		Ref.player_data = Player_Data.new()
		save_data()
		load_data()
	

The reason I’m writing the code this way is to reset the data in case it’s missing from the JSON file.
This is meant to ensure that if I update the game in the future and introduce new variables, they can still be added to older save files without causing errors.
