See section 5 on post. Find the second screenshot and find the yellow '! functions' Read this post as a sort of add-on / follow-up, whatever you want to call it!

Well, whenever you build your functions project and trying to setup your emulating environment, and still seeing this kind or a warning on your output but simply ignoring it. Sure, many of you just ignore it, that's oké, it is not a big deal! See this post aa a kind of writing just for the ones who sometimes dive into the little tiny nifty details. As said, seeing this so called warning and you're pretty sure you aren't running multiple instances of the emulator suite then then it is most likely the existance of multiple log files named 'firebase-debug.log' are your friends to get rid of this warning giving you a nice and clean output without any yellow warns about 'multiple instances'. Just try steps: Prerequisite: you're sure about just running one instance of emulator suite. On PowerShell
