Attempt to index local 'data' (a nil value)?

First off, HAPPY NEW YEAR!

I'm having a datastore for my game, currently holding some character info and stats. The problem is, whenever I call the loadData() function. It gives me the error from the title.

local DSS = game:GetService("DataStoreService")
local TeleportService = game:GetService("TeleportService")
local playerData = DSS:GetDataStore("PlayerData")

function generateDataKey(player)
	local ret = "user_"..player.UserId
	return ret
end

function generateDataTable(player)
	local dataTable = {
		magicType = player.PlayerData.MagicType.Value,
		magicLevel = player.PlayerData.MagicType.MagicLevel.Value,
		magicXP = player.PlayerData.MagicXP.Value,
		magicXPN = player.PlayerData.MagicXPNeeded.Value,
		magicEnergy = player.PlayerData.MagicEnergy.Value,
		levels = player.PlayerData.Levels.Value,
		xp = player.PlayerData.Levels.XP.Value,
		xpn = player.PlayerData.Levels.XPNeeded.Value,
		silver = player.PlayerData.Silver.Value,
		hp = player.PlayerData.HP.Value,
		
		hair1 = player.PlayerData.Hair1.Value,
		hair1Color = player.PlayerData.Hair1Color.Value,
		hair1Offset = player.PlayerData.Hair1Offset.Value,
		hair2 = player.PlayerData.Hair2.Value,
		hair2Color = player.PlayerData.Hair2Color.Value,
		hair2Offset = player.PlayerData.Hair2Offset.Value,
		skinColor = player.PlayerData.SkinColor.Value,
		face = player.PlayerData.Face.Value,
		shirt = player.PlayerData.Shirt.Value,
		shirtColor = player.PlayerData.ShirtColor.Value,
		pants = player.PlayerData.Pants.Value,
		pantsColor = player.PlayerData.PantsColor.Value
	}
	
	return dataTable
end

function saveData(player)
	local key = generateDataKey(player)
	local data = generateDataTable(player)
	playerData:SetAsync(key, data)
end

function inputData(player, data)
	player.PlayerData.MagicType.Value = data.magicType

	player.PlayerData.Pants.Value = data.pants
	player.PlayerData.PantsColor.Value = data.pantsColor	
end

function loadData(player)
	local key = generateDataKey(player)

I have other places that use the same format of script. On the other places, it works well. But on my current place, it gives the error.
