You are trying to get the value of the field before ACF has saved that value. You need to run a function after ACF is done saving so that there is a value to get. You do this by using acf/save_post https://www.advancedcustomfields.com/resources/acf-save_post/

function save_mytype($post_id) {
  if (get_post_type($post_id) == 'mytype' ){
    $file = get_field('pdf', $post_id);
    $url = $file['url'];
    $post = array(
      'ID' => $post_id
    );
    if ($url != '') {
      $post['post_content'] = '[flipbook pdf"'.$url.'" theme="light"]';
      //createNewsItem($post);
    }else{
      $post['post_content'] = 'Something is wrong';
    }
    // remove filter to avoid infinite loop
    remove_filter('acf/save_post', 'save_mytype');
    wp_update_post($post);
    add_action('acf/save_post', 'save_mytype');
  }
}
add_action('acf/save_post', 'save_mytype');
