[Help] Can't access source for a client call inside a triggered event

RegisterServerEvent("robberies:policeCheck")
AddEventHandler("robberies:policeCheck", function()
	TriggerEvent('es:getPlayers', function(players)
		local nbPolice = 0
		local queriesCompleted = 0
		local queriesSent = 0
		-- Looping through players one by one
		for i,p in pairs(players) do
			-- Fetching the job of the current player using their steamid given by es
			queriesSent = queriesSent + 1
			MySQL.Async.fetchAll('SELECT job FROM(SELECT * FROM users WHERE identifier = @identifier) as tempTable', { ['@identifier'] = p.getIdentifier() }, function(result)
				-- If we find a cop count up our cop count by one
				if result[1].job == "police" then
					nbPolice = nbPolice + 1
				end
				-- Once a query finishes we count up the queries completed
				queriesCompleted = queriesCompleted + 1
			end)
		end
		-- Since it's an asynchronos query, it's going to try and run this code without waiting for our data, which is stupid
		-- So we're waiting for all the queries to complete, checking every 1/10 of a second, there should be one query per player
		local timeWaited = 0
		while queriesCompleted ~= queriesSent and timeWaited < 10 do
			Wait(100)
			timeWaited = timeWaited + 0.1
		end
		-- If we've waited longer than 10 seconds for the queries to finish then we need to look at this code again
		-- Or the DB crashed and that's worse, but not my fault, probably
		if timeWaited > 10 then
			TriggerClientEvent("robberies:noFuckingESXCompatibilityDebugging", -1, "A robbery has timed out, please contact your an administrator")
			return
		end
		local report = "There are " .. nbPolice .. " detected"
		TriggerClientEvent("robberies:noFuckingESXCompatibilityDebugging", -1, "There are " .. nbPolice .. " detected")
		TriggerClientEvent("robberies:StartRobbery", source, nbPolice)
	end)

	-- The call will at least run out here but I need it to wait for the above code to run which it wont do
	--TriggerClientEvent("robberies:StartRobbery", source, nbPolice)
end)

I need to send the StartRobbery call. If I do it withing the triggered es event source is nil, if I do out outside then the two run in parallel but I need one to wait for the other.

Hi,

source is nil because you’re in an async callback, you need to store source in a local variable (like _source) before the trigger and you good
