**ImagesType**

ProjectCrudController

public function configureFields(string $pageName): iterable
    {
        return [
            IdField::new('id')->hideOnForm()->hideOnIndex(),
            IdField::new('uuid')->hideOnForm()->hideOnIndex(),

            TextareaField::new('images')->setFormType(VichImageType::class)
        ];
    }

我有类“应用\实体\项目”是不可上传的.enter image description here请告诉我，我做错了什么.
尝试使用FormType添加新字段，替换为其他类型
