Binding from a Strimzi CR is not properly decoded

[lburgazzoli]

I've created the following KameletBinding using a pre-built container image that should bridge Kafka and Slack.

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: kafka-to-slack
  annotations:
    "trait.camel.apache.org/container.image": "quay.io/rhoas/cos-connector-slack:main-65c1e78930846874d2c0414db67bcc60302e9943"
    "trait.camel.apache.org/kamelets.enabled": "false"
    "trait.camel.apache.org/jvm.enabled": "false"
    "trait.camel.apache.org/mount.configs": "[ \"secret:slack\" ]"
spec:
  source:
    ref:
      kind: Kafka
      apiVersion: kafka.strimzi.io/v1beta2
      name: rhoc-cluster
    properties:
      topic: datagen-out
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: slack-sink
    properties:
      channel: "#demo"
      webhookUrl: "foo/bar"

However in the resulting integration code, the Kafka ref is translated to Knative

apiVersion: v1
kind: ConfigMap
metadata:
 name: kafka-to-slack-source-000
data:
 content: |
   - route:
       from:
         steps:
         - to: kamelet:cos-slack-sink/sink
         uri: knative:endpoint/rhoc-cluster?apiVersion=kafka.strimzi.io%2Fv1beta2&kind=Kafka&topic=datagen-out
       id: binding

I would expect this binding to decode the Kafka ref to a kafka endpoint/kamelet in the generated code

so it turn out that the strimzi addon supports only the KafkaTopic CRD and I've tested that it works however, the camel-k operator should not fallback to knative if the ref cannot be resolved by any other addon.
