Symfony2 + SonataAdmin + VichUploaderBundle — поле загрузки изображения

Последние несколько дней пытались, будучи новичком в Symfony, найти хорошее решение по интеграции поля загрузки изображений в существующую сущность в Sonata Admin. Я гуглил и следую доступным путеводителям, но, к сожалению, я не могу понять это.

Настройка, как указано в заголовке

Symfony2
SonataAdmin
VichUploaderBundle

В данный момент я застрял со следующей ошибкой:

"Catchable Fatal Error: Argument 1 passed to Beautify\BeautiesBundle\Entity\Beauty::setImageFile() must be an instance of Symfony\Component\HttpFoundation\File\UploadedFile, instance of Symfony\Component\HttpFoundation\File\File given, called in /Users/gmf/symfony/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php on line 438 and defined in /Users/gmf/symfony/src/Beautify/BeautiesBundle/Entity/Beauty.php line 75 "

Поле загрузки изображения отображается правильно, и я получаю сообщение об ошибке после отправки.

Это строка 75:

/**
* If manually uploading a file (i.e. not using Symfony Form) ensure an instance
* of 'UploadedFile' is injected into this setter to trigger the  update. If this
* bundle's configuration parameter 'inject_on_load' is set to 'true' this setter
* must be able to accept an instance of 'File' as the bundle will inject one here
* during Doctrine hydration.
*
* @param File|\Symfony\Component\HttpFoundation\File\UploadedFile
*/
public function setImageFile(UploadedFile $image = null)
{
$this->imageFile = $image;

if ($image) {
// It is required that at least one field changes if you are using doctrine
// otherwise the event listeners won't be called and the file is lost
$this->updatedAt = new \DateTime('now');
}
}
