There is a workflow which should be triggered by a disconnect event, this workflow is being used from many years now and having no syntax errors.
But from few days, when I created disconnect event in quality system, workflow gets created but remains in READY state for some time and then goes in ERROR state.
The reason of ERROR status is "Error when loading the callback component (work item xxx)". Also shows that "No Agent Available" in Agent column in SWI1.
I am not getting why suddenly it started going in ERROR state for the same data for which workflow was created last week.
As I am creating workflow in Quality system, so I am sure there is no changes done on template. It looks either with some system enviroment or user authorization!
