How would I solve this invisible Lua Code Error??? Any way to prevent this in the future???

I have come across an error in my code, but output apparently doesn't show any error, I'm curious to know what that error is. I've tried numerous things, such as printing outputs and checking the values being printed. Here's the code:

Players = game.Players:GetChildren()
Players1 = {}
Sniper = ""

function RandomSniper()
    local Random = math.random(0,#Players1)
    Sniper = Players1[Random]
    print(Sniper)
    return true
end

function PlayerToNumber()
    if game.ReplicatedStorage.InfoValue == "Intermission: 0" then
    for i,v in pairs(Players) do
        table.insert(Players1, i, v.Name)
        print(Players1[i])
    end
end
end

function SniperToPosition()
    print(RandomSniper())
    if RandomSniper() == true then
        local Sniper1 game.Players:FindFirstChild(Sniper)
        Sniper1.Character.Torso.Position = game.Workspace.SpawningPart.Position + Vector3.new(0,5,0)
        local Gun = game.ServerStorage.Sniper:Clone()
        Gun.Parent = Sniper1.Backpack
    end
end
PlayerToNumber()
RandomSniper()
SniperToPosition()
