      Install Knative eventing
      Install Kogito operator
      Create default broker:

      apiVersion: eventing.knative.dev/v1
kind: Broker
metadata:
  name: default

      Create KogitoInfra pointing to the broker:

      apiVersion: app.kiegroup.org/v1beta1
kind: KogitoInfra
metadata:
  name: kogito-knative-infra
spec:
  # bind Knative Broker with our own service
  resource:
    apiVersion: eventing.knative.dev/v1
    kind: Broker
    name: default

      Create KogitoRuntime using the KogitoInfra:

      apiVersion: app.kiegroup.org/v1beta1
kind: KogitoRuntime
metadata:
  name: process-knative-quickstart-quarkus
spec:
  replicas: 1
  # see the Dockerfile in this directory to know how to build this app locally
  image: quay.io/<yournamespace>/process-knative-quickstart-quarkus:latest
  # we bind our application with Knative env
  infra:
  - kogito-knative-infra

      Check Kogito operator log.

    Description

      When KogitoInfra pointing to Knative broker is used in KogitoRuntime then nil pointer dereference is thrown in operator.

          is caused by

          Task - Represents a small unit of work that is not end-user facing. KOGITO-4059 Refactor Kogito operator into internal and core component

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
