Describe the bug

When importing { auth } from '@clerk/nextjs/server' in a Next.js layout component, the application crashes during preview mode (pnpm preview) but works correctly during development mode (pnpm dev).

Code Example

// app/(admin)/layout.tsx
import { auth } from '@clerk/nextjs/server';

export default async function AdminLayout({ children }: { children: React.ReactNode }) {
  const { userId } = await auth();
  // ... rest of component
}

Screenshot

Steps to reproduce

1. Import { auth } from '@clerk/nextjs/server' in a layout file (e.g., app/(admin)/layout.tsx)
2. Run pnpm dev - application works correctly
3. Run pnpm preview - application crashes

Expected behavior

The application should work correctly in both development and preview modes when importing from @clerk/nextjs/server.

Additional context

This appears to be a compatibility issue between @clerk/nextjs/server and the OpenNext Cloudflare adapter. The import works in standard Next.js development mode but fails when using the OpenNext Cloudflare build/preview pipeline.

Note: I am using the cache component feature (cacheComponents: true in next.config.mjs). This may be related to the issue.

// next.config.mjs
const nextConfig = {
  cacheComponents: true,
  cacheLife: {
    default: {
      stale: 60 * 60 * 24 * 1, // 1 day
      revalidate: 60 * 60 * 24 * 2, // 2 days
      expire: 60 * 60 * 24 * 7, // 1 week
    },
  },
};

• Package: @opennextjs/cloudflare@1.14.7
