title: Laravel 8: error when routing a GET to any view and receiving a error "Trying to get property 'user_id' of non-object"
body: <p>I've created a new Laravel 8 app with Jetstream and Livewire. When I make a GET request to any view an ErrorException is launched with message</p>
  <blockquote>
  <p>Trying to get property 'user_id' of non-object</p>
  </blockquote>
  <p>on navigation-dropdown.blade.php which is automatically generated by Jetstream\Livewire. I've looked for this <code>user_id</code> and didn't found on any part of the code.</p>
