SendChatMessage help

[weasoug]

HEY ALL, I have seen this 1 time but now a few others have, on my autoress code you get an error, it seems to be to do with the SendChatMessage when in combat, a message will say cant till xamount of time.

1x SendChatMessage(): Invalid escape code in chat message:
<in C code>: ?
<in C code>: in function `SendChatMessage'
wIn1-5.0\wIn1.lua:131: in function `?'
wIn1-5.0\wIn1.lua:617: in function <wIn1\wIn1.lua:616>

Locals:
(*temporary) = "Thanks for the rez! I still have 14 |4second:seconds; until I can accept it."
(*temporary) = "WHISPER"
(*temporary) = nil
(*temporary) = "nameremoved"

the error here seems to be todo with the event hand, of what is not near the main code

	local frame = CreateFrame('Frame')
	frame:Hide()

	for event, handler in pairs(eventHandlers) do
		frame[event] = handler
		frame:RegisterEvent(event)
		eventHandlers[event] = nil
	end

	frame:SetScript('OnEvent', function(self, event, ...)
		self[event](...)
	end)

but the error it self

	eventHandlers['RESURRECT_REQUEST'] = function(name)
		if not (UnitAffectingCombat('player') or UnitAffectingCombat(name)) then
			local delay = GetCorpseRecoveryDelay()
			if delay == 0 then
				AcceptResurrect()
				DoEmote('thank', name)
			else
				SendChatMessage(("Thanks for the rez! I still have %d |4second:seconds; until I can accept it."):format(delay), 'WHISPER', nil, name)
			end
		end
	end

anyhelp would be great, thanks
