Symfony vichUploader tmp文件不存在

Question

错误如下：

            $builder
                ->add('name')

                ->add('frontImage', VichImageType::class, array(
                    'required' => false,
                ));
    

My config file:
<pre>
vich_uploader:
    db_driver: orm
    mappings:
        category_image:
            uri_prefix:         /images/categories

            parent:

              joinColumn:
                referencedColumnName: id
                onDelete: CASCADE
              gedmo:
                - treeParent

        lifecycleCallbacks: {  }

resources/Config/vich_uploader中的配置：

    AppBundle\Entity\Category:
        frontImage:
            mapping: category_image
            filename_property: frontImageName

救命啊！

问题已修复。问题出在基本控制器上，我使用了如下内容：

Request::createFromGlobals() 

一切似乎都很顺利
