If a pre-process rule fails how can it been seen if the incident hasn't been created?

Hello,

If a pre-process rule fails how can it been seen if the incident hasn't been created?

Could be that the the incident is created anyway?

Just to set in context:

A pre-process is created to introduce the playbook procedure documentation in the layout.

If it fails how can be checked?

I haven't seen this happen to me specifically but I would say to take a look in the /var/log/demisto/server.log file for any traces of errors like these.
