    • 2023 Week 09-11 (from Feb 27), 2023 Week 12-14 (from Mar 20)

    Description

      Users should be allowed to choose if they want to send the request data in a plain JSON object (default) or in a CloudEvent object.

      The CloudEvents specification defines two ways of sending messages: "structured-mode" and "binary-mode".

      https://github.com/cloudevents/spec/blob/main/cloudevents/spec.md#message

      When using CloudEvents, Kogito must validate if the function argument is a valid CE, use the "structured-mode" and set "Content-Type" as "application/cloudevents+json; charset=UTF-8".

      When not using CloudEvents, Kogito must validate if the function argument is not a CE. Otherwise throw an error. (CE are not allowed when 'asCloudEvent' = false)

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
