Debugging and error handling
This chapter touches on two subjects that are intrinsically linked, though their use is different.
Debugging is the act of running through your process, either step by step or as a whole,
directly from the PReS Workflow Configuration tool, in order to detect and resolve issues with
your process.
Error handling, on the other hand, occurs when your configuration has been sent to PReS
Workflow services, and are running in "production" mode. The automated handling of errors
within your processes will have a large impact on recovering from errors as they happen during
production.
About error handling
When your process is running, or during debugging, it may happen that the task that is currently
running causes an error, and the task fails. For example, when trying to save to a folder that
does not exist, or printing to a printer that cannot be found.
When such an error occurs, in most cases you would want to be aware of it and to take certain
actions in order to correct or report the error. This is where our error handling features come in
handy.
Most of the tasks, branches and conditions included in your process can have their own error
handling behavior, with the exception of Comments, the Input Error bin task, and older legacy
tasks from previous versions of Workflow that did not have error handling.
By default, when an error occurs, the task is skipped and the unmodified job file is passed on to
the next task. You can overwrite this behavior by changing the options of the On Error tab of
the process - which sets the default error handling behavior for all the tasks in that process - or
of an individual task.
