Flow Designer Event Trigger to send email not working with San Diego upgrade

[Luis Roman]

Problem: “Snow Access Email is not working in San Diego for Snow Access Request Cat Item. I submitted this RITM and when it completed, the email should have been created. I looked at the flow context and I don't see any errors. The event fired. The email simply did not generate. It fails to create the email in 016, 001 and 002. So it's definitely a consistent issue in San Diego”

Background: A FlowDesigner workflow for one of our catalog items named: Snow Request Flow. Now with the upgrade to San Diego the code (Event Action) below does not work. The event name to trigger the event did not send the  email notification or was ignore. Could someone provide expert guidance to correct the issue with the San Diego release? Not sure where to start to determine corrective action? The event was working before the upgrade and nothing has been change. The issue details are below.

Your collaboration and expert guidance will be appreciated.

Are the records created in table sysevent as expected?

[Luis Roman]

Yes, they are.

In that case the problem is not with the flow. Perhaps the recipient is not active or has disabled notifications, or some mail script errors out or something.

[Luis Roman]

The recipient is active and notifications for that user is not disable. So the other other option you suggested is the "mail script error". How can I check if there is an error?
