Why doesn't my custom Adonis plugin command work?

Here is the code:

server = nil -- Mutes warnings about unknown globals
service = nil
return function()
	server.Commands.Gun = {
			Prefix = server.Settings.Prefix; 
			Commands = {"gun"}; 
			Args = {"player"}; 
			Description = "The said player gets a gun."; 
			Fun = true; 
			Hidden = false; -- 
			AdminLevel = "Moderators"; 
			Function = function(plr,args) 
				for i,p in pairs(service.GetPlayers(plr,args[1])) do 
					game:GetService("InsertService"):LoadAsset(116693764).Parent = plr.Backpack			
			end
		end
	}
end
