`react-server` condition breaks AppRouteRouteModule

[camflan]

The problem

Using react-server condition breaks the AppRouteRouteModule import

Reproduction steps

https://github.com/camflan/nextjs-ntarh-react-server

Additional context

• Node version: 22
• TypeScript: yes, version 5.7.x
• List of installed packages: nextjs 15.1.7

Relevant log lines:

Error: next-test-api-route-handler (NTARH) failed to import AppRouteRouteModule

  This is usually caused by:

    1. Using a Node version that is end-of-life (review legacy install instructions)
    2. NTARH and the version of Next.js you installed are actually incompatible (please check documentation and/or submit a bug report)

  Failed import attempts:

    - _react.default.createContext is not a function
    - Cannot find module 'next/dist/server/future/route-modules/app-route/module.js'

This error originated in "src/app/api/v1/my-first-route/__tests__/route.test.ts" test file. It doesn't mean the error was thrown inside the file itself, but while it was running.```
