Model:SetPrimaryCFrame() failed because no PrimaryPart has been set, or the PrimaryPart no longer exists. Please set Model.PrimaryPart before using this. - Stack Begin - Script 'ServerScriptService.SpawnCar', Line 6 - Stack End

this is the script

game.ReplicatedStorage.CarEvents.SpawnCar.OnServerEvent:Connect(function(player, vehicle)
    local clonedvehicle = game.ReplicatedStorage.Vehicles[vehicle]:Clone()
    clonedvehicle.Parent = workspace
    clonedvehicle.Name = player.Name.."'s Car"

    clonedvehicle:SetPrimaryPartCFrame(game.Workspace[player.Name].Head.CFrame)
    clonedvehicle:MakeJoints()
end)
