I need like a middleware that executes the getSession() server action and then if it doesn't return null it executes the next server action but I can't figure out why, I've tried multiple things with adding/removin async, passing the function reference instead of executing it but I always get the same error: "Error: A "use server" file can only export async functions, found object."

"use server";

import protect from "@/lib/protect";


export const display = async () => {
    return "ok"
};


export default protect(display)

//@/utils/protect.ts
"use server"
import { getSession } from '@/actions/login';

export default async function protect(fn) {
        if(await getSession()) {
            return await fn();
        } else {
            throw new Error("invalid session")
        }
        
}

Also Is there a way to manage the return status code like for example if I have a server action and I want to make it always return 404 how can I do that soo I can manage the response from the client through .catch()?
