Why isn't Roblox able to find my brick in a model?

New here, hoping you get help me out. Before I paste the code I would like to give you a run down of what I am trying to do.

I have a Model in ServerStorage that is to get copied and placed into Workspace, after it is moved to Workspace, the code will check for certain conditions and then move the player(s) to a certain brick named "SpawnPoint" that is inside that newly moved Model. However, I keep getting the error attempt to index a nil value

models = game.ServerStorage.blah:GetChildren()
function movemodel() 
    t = models[math.random(1, #models)]:clone() 
    t.Parent = game.Workspace

end

while true do wait()
    wait()
    movemodel()
    wait(5)
    for i, v in pairs(game.Players:GetPlayers()) do
    if v.TeamColor == BrickColor.new("Bright yellow") then
    v.Character.Torso.CFrame = game.Workspace:FindFirstChild("SpawnPoint").CFrame + Vector3.new(0,3,0)

        end
    end
