[Help] Issue with triggering a client-side event within a server-side event handler

FiveM Resource Development Discussion

I seem to be having an issue triggering a client event from with a server event.
I have thread that waits around 15 seconds from when the player loads into the server before triggering a server event. In the server event it retrieves some data from a database then sends it back to the client using a different event. The problem is it never works for the first player who joins but it does work if you reconnect or if you’re not the first player to join.

Anyone have any idea what is happening?

-- Client side event triggering
Citizen.CreateThread(function()
    Citizen.Wait(15000)
    TriggerServerEvent("reqData")
end)

-- Server-side handling of request
AddEventHandler("reqData", function()
	if GetIdFromSource("steam", source) then
		local SteamID = GetIdFromSource("steam", source)	
		if SteamID ~= nil then				
			MySQL.Async.fetchScalar("SELECT `value` FROM `database` WHERE `steamid` = @steamid", {['@steamid'] = SteamID}, function(queryResult)
				if queryResult ~= "[]" or nil then
					TriggerClientEvent('recData', source, queryResult)
                end
			end)
		end
	end
end)

-- Client-side data handling
AddEventHandler("recData", function(result)
	-- code here doesn't get triggered at all
end)

source won’t be retained across callbacks, try a local source = source
