process.env problems

I'm trying to run pre-existing node code with deno. https://gremlich.me/software-engineering/2024/using-next-with-deno/ fails for me just like most other code due to process.env not working. Is there some trick that I'm missing?

I

export DENO_FUTURE=1

export DENO_FUTURE=1

deno run -A --unstable-fs npm:next dev

deno run -A --unstable-fs npm:next dev

results in

error: Uncaught (in promise) ReferenceError: process is not defined

error: Uncaught (in promise) ReferenceError: process is not defined

This seems like it should work since i'm running stuff via npm:, which turns on all the legacy stuff.

One can use Next.JS with Deno finally!
