[BUG] Private environment variables not working on Vercel

[hankmander]

Describe the bug

If we take the following config from the documentation Vercel gives us ReferenceError: Oxygen is not defined . How are we supposed to use private environment variables on Vercel?

export default defineConfig({
  privateStorefrontToken:
    Oxygen?.env?.PRIVATE_STOREFRONT_API_TOKEN,
});

Additional context

• Hydrogen version 1.6.1
