Not workin with PHP 8

[pmoreno-rodriguez]

Hello.

I have two versions of PHP, 7.3 and 8 installed. With the same web page in Grav, the one loaded with PHP8, it shows this error:

C:\xampp\htdocs\grav\user\plugins\shortcodes\classes\Autoloader.php
        // Load class
        if (stream_resolve_include_path($file)) {
          return include_once($file);
        }
 
        return false;
      }
    }
 
    return false;
  }
 
  /**
   * Registers this instance as an autoloader
   *
   * @param bool $prepend Whether to prepend the autoloader or not
   */
  public function register($prepend = false)
  {
    spl_autoload_register([$this, 'autoload'], false, $prepend);
  }
 
  /**
   * Unregisters this instance as an autoloader
   */
  public function unregister()
  {
    spl_autoload_unregister([$this, 'autoload']);
  }
}
 
Arguments
"spl_autoload_register(): Argument #2 ($do_throw) has been ignored, spl_autoload_register() will always throw"

Is this plugin compatible with PHP 8?
