Table expected, got object?

I have a datastore script which is supposed to save the players stats and inventory. Why do I get the error: "20:07:45.026 - ServerScriptService.DSHandler:26: bad argument #1 to 'pairs' (table expected, got Object)"? The error occurs at line 26.

Here is the code:

statStore = game:GetService('DataStoreService'):GetDataStore('onepiheceaeikenicksicasaw5')
invStore = game:GetService('DataStoreService'):GetDataStore('inventorysicahiyoaeike3')
game.Players.PlayerAdded:connect(function(plr)
	-- OUR VARIABLES WEEEEEE
	local uniquekey = 'id-'..plr.userId
	local sup = Instance.new('Folder', plr)
	sup.Name = 'Data'
	local cash = Instance.new('IntValue')
	cash.Parent = sup
	cash.Name = 'Beli'
	local hamon = Instance.new('IntValue')
	hamon.Parent = sup
	hamon.Name = 'Fruit'
	local fac = Instance.new('IntValue')
	fac.Parent = sup
	fac.Name = 'Faction'
	local dmg = Instance.new('IntValue')
	dmg.Parent = plr
	dmg.Name = 'dmg'
	local GetSaved = statStore:GetAsync(uniquekey)
	local inv = invStore:GetAsync(uniquekey)
	if GetSaved then
		hamon.Value = GetSaved[1]
		cash.Value = GetSaved[2]
		fac.Value = GetSaved[3]
		for _,tool in pairs(invStore) do
			local item = game.ServerStorage.Items:FindFirstChild(tool):Clone()
			item.Parent = plr.Backpack
		end
	else
		local NumbersForSaving = {hamon.Value,cash.Value,fac.Value}
		statStore:SetAsync(uniquekey, NumbersForSaving)
	end
end)

game.Players.PlayerRemoving:connect(function(plr)
	local uniquekey = 'id-'..plr.userId
	local Savetable = {plr.Data.Fruit.Value,plr.Data.Beli.Value,plr.Data.Faction.Value}
	local inv = {}
	for _,v in pairs(plr.Backpack:GetChildren()) do
		if v:IsA("Tool") and v.Name ~= "Combat" then
			table.insert(inv,v.Name)
		end
	end
	statStore:SetAsync(uniquekey,Savetable)
	invStore:SetAsync(uniquekey,inv)
end)
