[HELP] WARNING: Bad argument @ 'addEventHandler' [Expected function at argument 3, got nil] and ERROR: Client triggered serverside event, but event is not added serverside

[NovaCrew]

So there are two errors: WARNING: pozarynew/synced_fire.lua:2: Bad argument @ 'addEventHandler' [Expected function at argument 3, got nil] 
and ERROR: Client (USAR|Plk.NovaCrew) triggered serverside event doCreateFire, but event is not added serverside.
I'm new so i'm not sure what to do. I've try to fix it on my on but i don't know how. What's wrong and how to fix it?

This is server side:

addEvent("fireExtinguished", true)
addEventHandler("fireExtinguished", root, fireExtinguishedHandler)
local fireModel = 2023
local fires = {}
addEvent("onFireExtinguished",true)
addEvent("onFireCreate",true)

function createFire(x,y,z)
	local fireElem = createObject(fireModel,x,y,z)
	setElementCollisionsEnabled(fireElem,false)
	local col = createColSphere(x,y,z+1,2)
	fires[fireElem] = {fireElem,col}
	addEventHandler("onColShapeHit",col,setFire)
	return fireElem
end

function setFire(elem,dim)
	if not dim then return end
	if not elem or not isElement(elem) then return end
	if getElementType(elem) == "player" then
		setPedOnFire(elem,true)
	end
end

function fireExtinguished(fireElem)	
	triggerEvent("onFireExtinguished",source,fireElem)
	destroyElement(fires[fireElem][1])
	destroyElement(fires[fireElem][2])
	fires[fireElem] = nil
end

and this is client side:

addEvent("makeSmokeAppear",true)

local fireModel = 2023

    local fire = engineLoadDFF("fire.dff",2023)
    engineReplaceModel(fire,fireModel)

WARNING: Bad argument @ 'addEventHandler' [Expected function at argument 3, got nil]
- fireExtinguishedHandler function is not exists, so you can't attach an event to this function.
- What can you do?
  1) Create this function.
  2) Remove the addEvent(...) and addEventHandler(...) in 1st and 2nd lines. (of course it's not a real solution, just eliminate the warning message)

ERROR: Client (USAR|Plk.NovaCrew) triggered serverside event doCreateFire, but event is not added serverside.
- Server try to trigger a client sided custom event, doCreateFire. But this event is not exists.
- What can you do?
  1) Make sure this event is exists on client side.
