Attempt To Index Nil With 'Parent' ?

I made a tool event, where when you press E it sends an event to the server (Client to Server) and then it clones a tool and puts it in your backpack. For some reason I keep getting errors that say "Attempt to index nil with 'Parent'.

Here is the Server Script attempt

game.ReplicatedStorage.radEv.OnServerEvent:Connect(function(Player, var)
    var.Archivable = true
    local clo = var:Clone()
    Player.Character.Archivable = true
    Player.Archivable = true
    clo.Parent = Player:WaitForChild("Backpack")
end)

game.ReplicatedStorage.gasSt.OnServerEvent:Connect(function(Player, var2)
    var2.Archivable = true
    local clone = var2:Clone()
    Player.Character.Archivable = true
    Player.Archivable = true
    clone.Parent = Player:WaitForChild("Backpack")
end)

I then tried to make it work on the local script but the same error occured

llocal HumanoidRootPart = game:GetService("Players").LocalPlayer.Character:WaitForChild("HumanoidRootPart")
local UI = game:GetService("UserInputService")
local lockerNSI = workspace.nsiLocker.Part
local idNSI = workspace.nsiID.ID
local player = game:GetService("Players").LocalPlayer


UI.InputBegan:Connect(function(keyCode)
    if keyCode.keyCode == Enum.KeyCode.F then


        if (lockerNSI.Position - HumanoidRootPart.Position).magnitude < 10 then
            if player:IsInGroup(redacted) then
                local var = game:GetService("ReplicatedStorage"):FindFirstChild("P2")
                game.ReplicatedStorage.radEv:FireServer(var)
            end
        end
        if (idNSI.Position - HumanoidRootPart.Position).magnitude < 10 then
            if player:IsInGroup(redacted) then
                local var2 = game:GetService("ReplicatedStorage"):FindFirstChild("Badge")
                game.ReplicatedStorage.gasSt:FireServer(var2)
            end
        end
    end
end)
