You are not passing the cid of the player to send the message.

Try this:

local pos = {x = 1089,  y = 1360,  z = 11}
local wall = 1304
local level = 100
local seconds = 60
local event = 0
 
local function reset(leverPos, cid)
	local lever = getTileItemById(leverPos, 1946).uid
	doTransformItem(lever, 1945)
	doCreateItem(wall, 1, pos)
	if(isPlayer(cid)) then
		doPlayerSendTextMessage(cid,21,"The pass has been closed!")
	end	
end
 
function onUse(cid, item, fromPosition, itemEx, toPosition)
	if(not isPlayer(cid)) then
		return true
	end
	if item.itemid == 1945 and getPlayerLevel(cid) >= level then
		doRemoveItem(getTileItemById(pos,wall).uid)
        doPlayerSendTextMessage(cid,21,"You have opened the pass, Beware!")
        event = addEvent(reset, seconds * 1000, getThingPos(item.uid), cid)
		doTransformItem(item.uid,item.itemid+1)
	elseif item.itemid == 1946 and getPlayerLevel(cid) >= level then
		stopEvent(event)
		doPlayerSendTextMessage(cid,21,"You have closed the pass!")
		doTransformItem(item.uid,item.itemid-1)
		doCreateItem(wall, 1, pos)
	end
	return true
end

Well he did not pass the cid argument to the delayed event, so cid is equal to nil.
You might want to change it so the lever still resets when there is no player, but the message is not sent then.
