how to shift from middleware.ts to proxy.ts?

[realtebo]

I renamed my middleware.ts as proxy.ts

It contains only

export { auth as middleware } from "./auth";

But I get this

Error: Turbopack build failed with 1 errors:
./proxy.ts
Proxy is missing expected function export name
This function is what Next.js runs for every request handled by this proxy (previously called middleware).

Why this happens:
- You are migrating from `middleware` to `proxy`, but haven't updated the exported function.
- The file exists but doesn't export a function.
- The export is not a function (e.g., an object or constant).
- There's a syntax error preventing the export from being recognized.

To fix it:
- Ensure this file has either a default or "proxy" function export.

Please, update next js installation guide

It should be

export { auth as proxy } from "./auth";

What would the change be if I used two separate configuration files for compatibility with non-Edge runtime? : https://authjs.dev/getting-started/migrating-to-v5#edge-compatibility.

My proxy.ts is set up as follows:

import authConfig from '@/lib/auth.config';
import NextAuth from 'next-auth';

export const { auth: proxy } = NextAuth(authConfig);

But it does not work. I get:

⨯ The file "./proxy.ts" must export a function, either as a default export or as a named "proxy" export.
This function is what Next.js runs for every request handled by this proxy (previously called middleware).
