Fs not working as intended(not at all)

So I have two parts of Fs code in my project one is to read the fs file and other writes to it and they work perfectly fine locally once deployed the Fs gets completely ignored the console log related to fs also gets ignored and I get no errors either

Node? On Fly, the fs module reads and writes to / just fine (code). It must be something in the way your app is setup, perhaps.

Can you share a bit more (of code) on how you’re doing it?
