Pipeline doesn't execute On Error

Sadly the "on fail"  is an AND and not an OR. In your case the notebook will only trigger if all parent activities fail and not just one of them.

This means you will have to create a notebook for each fail activity, which is indeed a pain if you have many activities in one pipeline. We created something similar, but with using the outlook activity to send an email if a specific step fails.

I have looked at using a notebook to just look at the whole pipeline and alert if the pipeline itself fails, but there are 2 downsides to that.

1: It won't give any detail, but the alert would tell you to go look at the log, since something is wrong

2: I would need to set  up an api-key etc, which I haven't done yet, and it would create more admin work

Hopefully this is of use to you.
