Hey there! We've found the following might help you get unblocked faster:

• 🧵 ReferenceError: File is not defined on Railway, not on local

• 🧵 Failed to build image for Next.js

• 🧵 buffer.File is an experimental feature and might change at any time (Next.js)

If you find the answer from one of these, please let us know by solving the thread!

hey! the issue is likely you're trying to use browser APIs (like File) in a server-side context, which doesn't work because Node.js doesn't have those

browser-specific objects.

you need to either:

- move File API usage to client-side only

- use Node.js equivalents (like Buffer or fs)

- add proper environment checks

basically you're mixing browser code with server code and that breaks things

let me know if this fixes it, and if not we'll look for another solution. share me a link to your codebase in that case - might be hard to fix without further context.

Hey I'm still having some problems here is my code, sorry I'm just not an expert hehe.

Upgrade Node.js to v18 or newer

Appreciate the amazing feedback guys, tried it all and it's finally working.
