[ERROR] addons/killerinfo/lua/autorun/server/sv_killmsg.lua:14: attempt to call method 'GetRoleString' (a nil value)

	hook.Add("DoPlayerDeath", "KillMessage", function(vic, atk, inf)
		net.Start("killmessages")
		net.WriteEntity(atk)
		net.WriteEntity(vic)

		if atk:IsPlayer() and atk:GetRoleString() == "traitor" or "innocent" or "detective" and vic:GetRoleString() == "traitor" or "innocent" or "detective" then
			net.WriteString(tostring(inf))
		  net.WriteString(inf:GetDamageType())
			net.WriteString(atk:GetRoleString())
			net.WriteString(vic:GetRoleString())
			net.WriteString(vic:LastHitGroup())
		else
			net.WriteString(tostring(inf))
			net.WriteString(inf:GetDamageType())
			net.WriteString("world")
			net.WriteString(vic:GetRoleString())
			net.WriteString(vic:LastHitGroup())
		end
	end)

so why is GetRoleString nil now if i die on falldamage or the nether in minecraft_b5?

I can only assume that GetRoleString is in the Player metatable, not the Entity metatable, and the attacker for fall damage or for triggers are of entity type. Check if the attacker is a player first.
