JSON Message Missing Vital Fields

[thenewguy]

I have recently observed notifications are sent with the key eventType instead of notificationType. The SES docs still state to expect notificationType per https://docs.aws.amazon.com/ses/latest/DeveloperGuide/notification-contents.html

However, I've found other issues related to the problem:

• Received SES webhook of type 'Notification' but couldn't understand payload mautic/mautic#8903
• SES-Feedback using 'notificationType' instead of 'eventType' spatie/mailcoach-support#217

An interesting comment at mautic/mautic#8903 (comment):

If you are using a SES Configuration Set (by setting the custom mail header X-SES-CONFIGURATION-SET), the bounce event generated by SES is slightly different than if you configure bounce management globally. In fact, the difference is just a JSON key. It is eventType instead of notificationType.

We are using the X-SES-CONFIGURATION-SET header. As such, it seems like we need to support both.

The simplest solution seems to be copying eventType to notificationType if notificationType is not set.
