Problem description

Currently in CAMARA CloudEvents Model, Exception 504 (TIMEOUT) is not considered.

It is proposed to consider this exception for Timeout scenario where API Server generates a timeout (e.g. communication failure with BE component).

To be discussed within Commonalities.

Possible evolution

If agreed, to enhance Notifications and Subscription artifacts to incorporate this exception:

• https://github.com/camaraproject/Commonalities/blob/main/artifacts/notification-as-cloud-event.yaml

Also to check whether some description enhancement is required in section 12 of API Design Guidelines document.
