What is wrong with this script?

I tried out i,v in pairs finally And It messed up...

for i,v in pairs(game.Workspace:GetChildren()) do
	v:remove() -- [[ Error| The Parent Property of Workspace.Terrain is locked. current parent:Workspace.new parent NULL ]]
end

The Terrain object is RobloxLocked, meaning it cannot be removed. To get around this and other objects that are RobloxLocked, use this:

for i,v in pairs(game.Workspace:GetChildren()) do
	if v.RobloxLocked == false then
		v:Destroy() -- Use :Destroy(), :remove() is deprecated.
	end
end
