Trying to check if a user is AlphaUser or not. Back-end dev is still implementing this so currently just using static variable (bare with me)

"use client";

import { useEffect } from 'react';
import { useRouter } from 'next/router';

const Home = () => {
  const isAlphaUser = true; // Replace this with the actual check once the API is ready
  const router = useRouter();

  useEffect(() => {
    // Check if the user is not an alpha user
    if (!isAlphaUser) {
      // Redirect to the /alpha route
      router.push('/alpha');
    }
  }, [isAlphaUser, router]);

  return (
    <main>
      {/* Your main content goes here */}
    </main>
  );
};

export default Home;

I get this error though:
