Why random spawning system don't work?

Hello, devs!

I was making trash system to a game. Don't know why it's not working. There are no errors on output. In script I was cloning Union and then changing position. Maybe union was the problem, but I don't know. Script is located in the model which has a part that size properties was used.

CODE:

while wait(math.random(1,3)) do
    local pos1 = math.random(-12,12)
    local pos2 = math.random(-12,12)

    local trash = game.ReplicatedStorage.Trash:Clone()
    trash.Position = Vector3.new(pos1, 10, pos2)
    trash.Anchored = false
    trash.Parent = game.Workspace
end

ERRORS:
