Describe the issue

When running a Next JS site using Authjs v5.0.0-beta.19 and next dev --turbo, I get the following error - "Error: headers was called outside a request scope", running next dev without the --turbo flag works as previous.

Authjs v5.0.0-beta.18
next dev (works)
next dev --turbo (works)

Authjs v5.0.0-beta.19
next dev (works)
next dev --turbo (causes the error)

How to reproduce

Running the command "npm run dev" when "--turbo" is enabled cause the application to error.
Running the command without "--turbo" works normally and both with and without work on the previous version (v5.0.0-beta.18).

Credential provider has been configured for the example, no inputs actually needed, user has been hardcoded.

Expected behavior

The session from "await auth()" should be returned.

Research direction

Start with the linked reproduction repository and run its npm run dev command with and without --turbo. Compare Authjs v5.0.0-beta.18 and beta.19 under Next.js 14.2.3, focusing on the reported headers request-scope error. Done means await auth() returns the session in turbo development mode without the error.
