## Error Type
Blocking Route

## Error Message
Route "/project": Uncached data was accessed outside of <Suspense>. This delays the entire page from rendering, resulting in a slow user experience. Learn more: https://nextjs.org/docs/messages/blocking-route


    at AppHomePage (src/app/(app)/project/page.tsx:17:38)
    at LogSafely (<anonymous>:null:null)

## Code Frame
  15 | export default async function AppHomePage() {
  16 |   // Check if user is authenticated and already a member
> 17 |   const session = await verifySession();
     |                                      ^

  19 |   if (session?.user && !session?.user.isProfileComplete) return redirect("/");

you need to add loading.tsx to your pages so they appear instantly. For private caching data from dynamic functions like cookies, you can use use cache: private ([see more](https://nextjs.org/docs/app/api-reference/directives/use-cache-private)). For none use related data use use cache directive.

Independed of that: your project is vulnable to [CVE-2025-55184 & CVE-2025-55183](https://nextjs.org/blog/security-update-2025-12-11). You want to fix those asap by upgrading to 16.0.10
