Allocate Gatekeeper Law Checklist Tasks process goes into error

I am testing the Gatekeeper law for Netherlands. I performed below actions

1. Create Sickness Absence Type
2. Attached the absence type to Gatekeeper law absence category
3. Created an long term absence for sickness.
4. Case Manger created absence case
5. Ran Scheduled process "Allocate Gatekeeper Law Checklist Tasks".

I tried this process yesterday and it worked fine and checklist generated for task manager. I tried to run this again today but the process went into error. The error log message is not enough to understand the cause. Any advise as how view the detail of the error would really help. I have attached error log for reference.Thanks
