Pre fetch WADO objects -dcm4chee-arc-light

[Amms]

 Hi,

           I am trying to prefetch WADO jpeg images during C-Move from external PACS to DCM4CHEE. For this I have configured simple use case and Storage as per https://github.com/dcm4che/dcm4chee-arc-light/wiki/Pre-fetch-of-WADO-objects.

        Attached the screenshot of the configuration done. After configured the details I performed a C-Move from my external PACS To DCM4CHEE . In the log the Export task is created and after 1 minute the task is sheduled > but later the task is failing with java.lang.NullPointerException

      Any suggestion to fix this issue ?
