Question

我正在尝试运行一个绝对最小的协调流来测试Data Hub Framework（DHF），但是该流每次都会失败。

创建新的协调流（默认设置，尝试使用空白模板并从实体定义创建）并尝试运行后，它将启动“收集器”过程，并几乎立即失败。跟踪文件或调试输出日志文件中没有记录任何信息。

从创建协调流到失败的调试日志为：

实体和流程如下：

关于可能是什么原因的任何想法？

在8010_ErrorLogs_1.txt中发现错误（已删除引用的文件名）：

2018-06-27 13:57:40.363 Info: Exception caught while transforming/[FILENAME].pdf-0-23213: XDMP-AS: $src as node() -- Invalid coercion: null as node()

请注意，同一错误在日志文件中发现了数千次，每行中[FILENAME]的值不同。
