I’m trying to get humanoid description from a player’s character onto an NPC.

game:GetService("ReplicatedStorage").Events.NOWAYYY:FireClient(game:GetService("Players").weakroblox35, {
Tix = "+T$250",
Killed = "",
Killer = game:GetService("Players").weakroblox35.Character		
})
--
local Description:HumanoidDescription? = information.Killer.Humanoid:GetAppliedDescription()
local clone = workspace.DummyRigForGUI:Clone()
clone.Humanoid:ApplyDescription(Description)
