The error comes from this part. Removing .process(proc) makes the route work.

function proc(e) {
    e.getIn().setHeader('RandomValue', Math.floor((Math.random() * 100) + 1))
}
[...]
    .process(proc)

@tadayosi can you report runtime issues to https://github.com/apache/camel-k-runtime ?

@lburgazzoli Oh, sure, will do from next time.
