Why doesn't this table saving work? And how to properly save a table?

So I have a table in a local script and i pass the table to a server script to save it

local script:

--this is how im passing the table to a server
remoteSaving:FireServer(table)

the table when i tested only had one value inside of it

server script (saving data):

remoteSaving.OnServerEvent:Connect(function(pl, table)
	Items = table
	ds1:SetAsync(pl.UserId, Items)
	print("saved data for"..pl.Name)
end)

then when a player joins i use PlayerAdded event to call a function for getting data, also in the same server script:

game.Players.PlayerAdded:Connect(function(pla)
	Items = ds1:GetAsync(pla.UserId) or {}
	remoteSaving:FireClient(pla, Items)
end)

and when I fire client with that table it crashes because my for loop where i go through the table acts like it has infinite amount of values in it

Anyone knows what im doing wrong?

il try to fix your script im sorry if this does not help

--Local Script
save = nil
thingys = {"a,b,c"}
thingys:FireServer(thingys)
print(thingys)
