如何在VichUploader中使用mimeType Assert？

当使用VichUploaderBundle上传任何文件时,此断言正在传递Symfony的表单验证:

/**
 * @Vich\UploadableField(mapping="product_media", fileNameProperty="path")
 * @Assert\File(
 *     mimeTypes = {"image/jpeg", "image/gif", "image/png", "video/mp4", "video/quicktime", "video/avi"},
 *     mimeTypesMessage = "Wrong file type (jpg,gif,png,mp4,mov,avi)"
 * )
 * @var File $pathFile
 */
protected $pathFile;

我看不出断言的问题.如何使用VichUploader验证文件类型？
