Error code. Can not understand. ???lllllllllllllllllllllllllllllllll

I have an error, I do not know how to solve it. Help me please.

The error itself:

Model:GetPrimaryCFrame() failed because no PrimaryPart has been set, or the PrimaryPart no longer exists. Please set Model.PrimaryPart before using this.

local Parent = script.Parent
local Config = Parent.Config
local Enabled = Config.Enabled
local model = Parent



local function DoorAnimation()
    if not Enabled.Value then
        Enabled.Value = true
        for i = 0, 17 do
            model:SetPrimaryPartCFrame(model:GetPrimaryPartCFrame() * CFrame.Angles(0, 0.1, 0))
            wait()
        end
        wait(2)
        for i = 0, 17 do
        model:SetPrimaryPartCFrame(model:GetPrimaryPartCFrame() * CFrame.Angles(0, 0.1, 0))
            wait()
        end
        Enabled.Value = false
        end
    end
Config.DetectEvent.OnServerEvent:Connect(DoorAnimation)
