URGENT: Module not found: Can't resolve 'fs'

[ForgeSolutions-JBrenner]

Summary

Hey all,

I have tried just about everything to resolve this but now i need some help. I have had a project running for a year now untouched, i went in to update a couple of env variable path names and pushed back to github and vercel and i get the following error:

`- error ./node_modules/next/dist/compiled/@vercel/og/index.node.js:17950:0
Module not found: Can't resolve 'fs'

https://nextjs.org/docs/messages/module-not-found

Import trace for requested module:
./node_modules/next/dist/server/web/spec-extension/image-response.js
./node_modules/next/server.js
./node_modules/@supabase/auth-helpers-nextjs/dist/index.js
./src/pages/_app.tsx`

I am running next 13.0.7 and for the life of me cannot figure out what is going on. Like i said the project has been running untouched perfectly for a year. I have referenced everything available and tried a multitude of different solutions without success.

It happens when server code somehow makes it to the code intended for the browser, because the browser doesn't have the fs module.

Could you show what's going on in _app? Did you make any changes there? or to any of its imports? Did you update packages?

It'd seem like some package is not making use fs on _app, which would crash out when trying to make a browser build.

It might be a transitive problem. _app imports moduleA, which uses moduleB, which in turn has some code that is meant for server side only. If this happens inside node_modules because a 3rd party moved code around, then it might "just happen", when trying to update a "few things" on a project.

if you use some function like getStaticProps? if so, it's quite possible that nextjs get data from server failed at build time and try to run getStaticProps on the client.
