How can I prevent this from happening?
I have a script that needs to get data from a model in ServerStorage but it keeps giving me this error: attempt to index a nil value
The script line is this:
for i,v in pairs(game:GetService("ServerStorage"):FindFirstChild("Data"):GetChildren()) do
Then it gets the data from it but sometimes it has nothing in it and it checks it any way returning a nil value and therefore returns an error. Do YOU know how to fix this?

Try:
Model = game.ServerStorage:FindFirstChild("Data")
for i, v in pairs (Model:GetChildren()) do
end
**I think the problem was ServerStorage doesnt work with GetService. Not 100% sure.

I think the problem here is that you don't have a statement that checks if Data exists. If Data doesn't exist but the script runs this line anyways, it will error because the script can't find Data! A way to fix this is to add an if statement checking if Data exists before running the code.
if game:GetService("ServerStorage"):FindFirstChild("Data") ~= nil then
for i,v in pairs(game:GetService("ServerStorage"):FindFirstChild("Data"):GetChildren()) do
I hope this helps!
