Next 15, React 19, with Turbopack -- Environment variables do not load on client at all (including NEXT_PUBLIC_

[nodeworks]

Summary

I'm using Next 15.1.3 with React 19.0.0 and turbopack. I have a .env.local file that contains some NEXT_PUBLIC_ variables which load fine on the server but do not load at all (undefined) on the client.

I am using App router.

It works fine without using turbopack so I'm confused if I missed something?

If I console.log(process.env) it's just an empty {}

In case anyone comes across this issue. The problem was doing the optional chaining.

This doesn't work:

process?.env?.NEXT_PUBLIC_SOME_VAR

this does:

process.env.NEXT_PUBLIC_SOME_VAR
