View errors on repeating (or rescheduled) timers #227
Description
Is your feature request related to a problem? Please describe.
When running a timer multiple times, it can be very useful to see the last result (exception if one was raised).
Describe the solution you'd like
Add an exception to the timer if the timer if not removed after a one-time run. It would be nice to have a function like timer_err(..) to get the error as a value.
Describe alternatives you've considered
As an alternative one has to view the node logs to see the error. It is not always easy (of even possible) to access this log.
