Using SharePoint 2013 Enterprise, Nintex workflow 2013 standard for SharePoint
List Workflow stopped unexpectedly with an error email at change state in some items. in workflow history, now it shows as cancelled or errored workflow.
While troubleshooting I clicked on the item with example ID - 1327 and then its associated workflow history, it shows workflow started at 5 Oct 2019 7:52 PM and ended at 5 Oct 2019 8:29 PM. But once I click on the link of workflow I can see still see workflow running.
The main problem is the item lost task associated with it. And hence users are not able to see the tasks in my tasks list. Also, I am running another workflow which calls Nintex service to give detail of the task associated with the item which gives result as empty and hence further process stops, which was unexpected to me.
Upon diagnosis, I found in the workflow which errored for some items, there is a delay in "Change state" action for this item was like 35 minutes, could be the reason why later item loose task details associated to it.
Screenshots are attached any help will be highly appreciated.
