Oracle11g APEX 5 get_blob不起作用

我正在从事Oracle APEX（Oracle APEX 5.03.00.03 on Oracle 11.2.0.1.0）项目，希望在经典报告中添加BLOB下载字段。当我尝试实现内置BLOB功能时，当我尝试使用下载功能时，会出现以下错误：

在此服务器上找不到请求的URL/apex/apex\u util.get\u blob

当我简单地显示包含BLOB的表的ID时，它似乎工作得很好

有人能告诉我为什么会收到这个错误消息吗

详细错误消息：

您需要将这些内容添加到页面中

隐藏的页面项，如P60\u DOC\u ID

一个文件浏览页面项目，比如P60_DOC

页头执行点之后的自动行提取过程，例如 取回文件

然后您可以按照以下方式实现内置BLOB函数：

APEX_UTIL.GET_BLOB_FILE_SRC('P60_DOC',DOC_ID,NULL,'inline')

供参考的项目和过程属性的屏幕截图
