This is my first game . I am making a save system and getting an error as follows:
Invalid get index ‘unlockedlevel’ (on base: ‘Dictionary’) . Searched for answers online and did not got any . Please help me


#variables

var coins = 0
var levels = []
var unlockedlevel = 1

#functions

#save game
func save_game():
	var save_file = File.new()
	save_file.open("user://save_game.save" , File.WRITE)
	var data = {
		"coins":coins,
		"unlockedlevel":unlockedlevel
	}
	save_file.store_var(data)
	save_file.close()


#load game
func load_game():
	var save_file = File.new()
	if !save_file.file_exists("user://save_game.save"):
		return
	save_file.open("user://save_game.save" , File.READ)
	var data = save_file.get_var()
	coins = data["coins"]
	unlockedlevel = data["unlockedlevel"] #error
	save_file.close()

If the words need to be scrunched together, I would suggest using “camel case” for key names, e.g. UnlockedLevel. That makes it a bit easier to read the name. I would also suggest checking for the key name in the dictionary:

if data.has("UnlockedLevel"):
    unlockedlevel = data["UnlockedLevel"]

That way, the game can be programmed to react to data that isn’t there. If the data isn’t being saved to a file, or the file doesn’t have the data, then that issue will have to be addressed.
