Kamel bind produces incomplete yaml files with -o yaml

[hguerrero]

When running kamel bind ... -o yaml the result is missing the apiVersion and kind lines.

Example:

kamel bind timer-source kafka-sink -p source.message="hola mundo" -p sink.topic="timer1" -p sink.brokers="uno" -p sink.username="dos" -p sink.password="tres" -o yaml

produces the following output:

  creationTimestamp: null
  name: timer-source-to-kafka-sink
  namespace: user1
spec:
  errorHandler: null
  sink:
    properties:
