Hello everyone!

I am making a UGC Code System but I have a error,
DataStoreService: CantStoreValue: Cannot store Dictionary in data store. Data stores can only accept valid UTF-8 characters. API: SetAsync, Data Store: CodeDataStore (x5)

Script :

local DataStoreService	= game:GetService("DataStoreService")
local RedeemDataStore 	= DataStoreService:GetDataStore("RedeemDataStore")
local CodeDataStore		= DataStoreService:GetDataStore("CodeDataStore")

local maxTries 			= 5
local tryCooldown		= 2 --seconds

local CodeManager = {}

local function createCode(codeName,code,INDEX)
	if INDEX > maxTries then
		warn(tostring(codeName).." could not be saved!")
		return
	end
	local success = pcall(function()
		CodeDataStore:SetAsync(codeName,code)
	end)

	if success then
		print("success")
		return
	end
	
	task.wait(tryCooldown)
	createCode(codeName,code,INDEX+1) --recursion
end

local function checkCodeName(codeName)
	local success,code = pcall(function()
		CodeDataStore:GetAsync(codeName)
	end)
	
	if success and code and code["active"] > tick() or code["active"] < 0 then
		return true,code
	end
	
	return false
end

function CodeManager.newCode(codeName,itemId,count,creatorId,lifeTime) --lifetime in seconds or -1 for infinite
	local newCode = {
		itemId = itemId,
		itemC  = count,
		active = tick() + (lifeTime > 0 and lifeTime) or (-2*tick()),
		
		
		creatorId = creatorId;
	}
	
	createCode(string.lower(codeName),newCode,1)
end

local function giveItem(player,code)
	
end

local function playerRedeemCode(player,codeName,data,code)
	local newData = table.insert(data["codes"],codeName)
	local success = pcall(function()
		CodeDataStore:SetAsync(player.UserId,newData)
	end)
	
	giveItem(player,code)
end


function CodeManager.redeemCode(player,codeName)
	local codeName 	 = string.lower(codeName)
	local state,code = checkCodeName(codeName)
	
	if state == true then
		local success,data = pcall(function()
			CodeDataStore:GetAsync(player.UserId)
		end)
		
		if success then
			if data["codes"] and not table.find(data["codes"],codeName) then
				playerRedeemCode(player,codeName,data,code)
			end
		else
			RedeemDataStore:SetAsync(player.UserId,{})
			data = {codes = {}}
			playerRedeemCode(player,codeName,data,code)
		end
	end
end

return CodeManager

Please help me!

what’s the value that you are giving to the “codeName” and “code” parameters?

The main issue was that OP didn’t use code and codeName correctly! Always check your types my guys!

Hope this helps someone!
