Page can be made visible with required fields missing?

In my blueprint author is a required field but you can create a new page and make it visible on the front-end without completing the author field and saving.

Regardless, the author field is empty

<?php if($avatar = $site->user($page->author()->value())->avatar()->crop(40)): ?>
  <img width="40" height="40" src="<?php echo $avatar->url() ?>" alt="avatar">
<?php endif ?>

And I get the following error:

Call to a member function avatar() on a non-object

How can I stop this error in the event a page is made visible with empty fields?

Thanks

You can check if the field is empty and only proceed if not. [untested]

<?php 
  // check if author field is not empty
  if ($page->author()->isNotEmpty()) {
    $author = $page->author()->value();

    // get the user if exists
    if ($user = $site->user($author)) {

      // get the avatar and crop it
      $avatar = $user->avatar()->crop(40);
    }
  }
?>

<?php if(!empty($avatar)): ?>
  <img width="40" height="40" src="<?php echo $avatar->url() ?>" alt="avatar">
<?php endif ?>

You can keep your template clean, if you move the logic to a controller.

Additionally, you could use permissions to prevent changing the status of a page unless the field is filled in: https://getkirby.com/docs/cheatsheet/permissions/panel-page-visibility
