### Part 2:
### Code
Here's the code for each relevant file that's causing the error:

File: ClientInsideServerLayout.tsx

'use server';

import { getSessionStatus } from "../ServerActions/isUserLoggedIn";
import ClientLayout from "./ClientLayout"
export const dynamic = 'force-dynamic'

export async function ClientInsideServerLayout() {
    const isLoggedIn = await getSessionStatus();
    return (
      <>
      <ClientLayout isLoggedIn={isLoggedIn}></ClientLayout>
      </>
    )
  }

File: ClientLayout.tsx

'use client'

import Link from 'next/link';
import { useRouter } from 'next/navigation'

// ... rest of the code ...

Here's the code for the RootLayout that I'm using:

// Existing RootLayout code
'use server';
import './globals.css';
import { getSessionStatus } from './ServerActions/isUserLoggedIn';
import { ClientInsideServerLayout } from './components/ClientInsideServerLayout';

// ... rest of the code ...

### Question
Can someone explain why this error is happening, and how can I fix it while keeping the layout update functionality when clicking the log-out button? I want to achieve this without having to refresh the page.

Any insights or suggestions would be greatly appreciated! Thank you!

is any of your layouts client components as once one part is client, the whole route below it is also?

and iirc putting "use server" at the top does nothing, the best thing you can do is [import server-only](https://nextjs.org/docs/getting-started/react-essentials#keeping-server-only-code-out-of-client-components-poisoning) to cause an error if imported from client component

You have to remove the use server. It is used to mark server actions not server components, and server action files have restrictions compared to server component files (e.g. you can only export async functions with serialisable signatures)

ahh it actually does it differently and not ignored

Thank you for your guidance on this issue. Removing the "use server" indeed fixed the specific error "Only async functions are allowed to be exported in a 'use server' file," and now the pages can compile successfully.

However, I'm still facing an issue with the behavior I wanted to achieve. Despite resolving that error, I still have to refresh the page manually when I log out so that the navbar updates correctly. It seems that the change has not resolved the underlying problem of the navbar not dynamically updating as intended.

Below, I've included a video link showing the behavior I'm currently getting, which is not the desired outcome. If you have any further insights or suggestions to help me overcome this obstacle, they would be greatly appreciated!

Thank you once again for your assistance!

This solved my issue! Thank you!
