Error teleporting player to random brick?

for i,v in pairs(game.Workspace:GetDescendants()) do
	if v.Name == "Spawnpoint" then
		local ChosenSpawn = (v[math.random(1, #v)])
		game.Players.LocalPlayer.Character.HumanoidRootPart.CFrame = ChosenSpawn.CFrame
	end
end

I'm trying to make a script so that it gets the descendants of the workspace to find all bricks named "Spawnpoint", and then making a random pick of one of the spawn bricks, and then teleporting the player to the brick.

Whenever I try to test the script in studio, I keep getting this error: attempt to get length of local 'v' (a userdata value) Any way I can fix this?

You're trying to use a length operator on an object.

local ChosenSpawn = (v[math.random(1, #v)])

I believe what you're wanting is:

local ChosenSpawn = (v[math.random(1, #(v:GetChildren()))])
