Redirect after checking in Nuxt Asyncdata

Question

I am running Nuxt and I have the below function. I want to check if authenticated then redirect to the login page if not. I am getting the error window is undefined This make since because it is my understanding that asyncdata() is evaluated server side. What is the correct way to redirect. I tried to use the redirect method in context but it just brings up my 404. Thanks

 async asyncData(context) {
    if (!context.authenticated) {
      window.location = `${config.url}/sign_in`;
    }
  }

context has a redirect function. Nuxt Docs

 async asyncData(context) {
    if (!context.authenticated) {
      context.redirect(`${config.url}/sign_in`);
    }
  }
