local DataStore = game:GetService("DataStoreService"):GetDataStore('Gay')



game.Players.PlayerAdded:Connect(function(player)
	local GotAsync = DataStore:GetAsync(player.UserId)
	
	if GotAsync then
		print(GotAsync.Tbl1)
	end
	
end)

game.Players.PlayerRemoving:Connect(function(player)
	
	local Tbl = {}
	local Tbl1 = {'ger','sdf','r2r'}
	local Tbl2 =  {}
	
	table.insert(Tbl,Tbl1)
	table.insert(Tbl,Tbl2)

	
	DataStore:SetAsync(player.UserId,Tbl)
end)

Whenever I try saving in the player removing it keeps saying

104: Cannot store Array in data store. Data stores can only accept valid UTF-8 characters.

so am i doing anythng wrong if so How can I save a table inside a table
