Hi Maciejs,


So now the deadlines are created at the database end. And at the scheduled time when the services are attempting to run we get an exception like this.

FYI, for now to make this piece work I'm just using DefaultEscalatedDeadlineHandler only. Not extending any custom handler. can you please let me know what am I missing here

Thanks,
