The exception occurs on VerifiableComponent.getVerifier() before even the parameters (including the scheme) are provided in verify().

It could be an outdated Camel SNAPSHOT as there was some fixes.

Also I assumed you have built all of the connector code prior to running this example. But try again as ASF CI server has built a new SNAPSHOT of Camel with latest code.

The example works for me locally just now
