      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.

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