ProfileStore Inventory Issues

[BedsheetGhostYT (Bedsheet Ghost)]

Hey all, I’ve been learning ProfileStore recently, as it seems like a good jumping off point for learning about Datastores. I’ve got the main profile saving system set up according to this YouTube tutorial.

I have two basic pieces of data: Cash, and the player’s inventory. The AddCash() function seems to work just fine, but it’s adding tools to the player’s inventory that just doesn’t work…

function Shared.AddCash(player: Player, amount: number)
	local data = Shared.GetData(player) -- GetData returns Profiles[profile].Data
	if not data then return end
	print("Data exists for "..player.Name)
	local cash = data.Cash
	
	data.Cash += amount
	print(`player has {cash} cash`)
	
	print(Shared.GetData(player))
end -- this works

I split the UpdateInventory() function into two parts, one that adds the item to the player’s profile Inventory, and one that adds the item to the player’s backpack:

function Shared.UpdateInventory(player: Player, item: string)
	local data = Shared.GetData(player)
	if not data then 
		warn("Data cannot be found for "..player.Name.." !")
		return
	end
	
	print("data exists")
	local inventory = data.Inventory
	table.insert(inventory, item)
	print("Inserted into inventory")
	
	print(Shared.GetData(player))
end

function Shared.AddToBackpack(player: Player, item: string)
	local data = Shared.GetData(player)
	if not data then 
		warn("Data cannot be found for "..player.Name.." !")
		return
	end
	
	print("data exists")
	
	local asset = ReplicatedStorage:WaitForChild("Assets"):FindFirstChild(item)
	if not asset then
		asset = ReplicatedStorage:WaitForChild("ModelAssets"):FindFirstChild(item)
	end
	print("Asset found.")
	
	if asset then
		asset.Parent = player.Backpack
	end
	
	print(Shared.GetData(player))
end

No matter which value I pass through this function, it always returns nil, and it’s driving me insane.

clickDetector.MouseClick:Connect(function(player)
	if not player then return end
	local item = script.Parent.Parent.Parent
	
	PlayerData.UpdateInventory(item.Name) -- somehow always ends up passing nil.
	print("added "..item.Name.." to inventory!")
	PlayerData.AddToBackpack(item.Name) -- same issue here.
	print("added "..item.Name.." to backpack!")
	
	item:Destroy()
end)

^^^
Example where I click on a tool and it adds the tool to the player’s inventory (in theory)

I really don’t know what I’m getting wrong here. If someone is able to help me figure out what I need to do to make a functioning inventory system here, please let me know! I’m new to DataStores in general and would really appreciate some assistance.

so looking through the code

in this function it calls for the player and the item name
function Shared.AddToBackpack(player: Player, item: string)

but you forgot to pass the player when calling the function
PlayerData.UpdateInventory(item.Name)
PlayerData.UpdateInventory(player, item.Name)

and do the same with PlayerData.AddToBackpack(item.Name)

PlayerData.AddToBackpack(player, item.Name)

omg that was really it
I wrote this at like 10:30PM last night. I think what happened was I somehow thought I was using RemoteEvents. Anway, rookie mistake I suppose. Thank you for your help!
