Platform : kamel Camel K Client 1.0.0-M4 on minikube 1.6.x using Knative serving/eventing v0.11.0 and CamelSource v0.10.3

When I try to deploy this JS integration

from('knative:channel/camel-test-channel')
    .convertBodyTo(String.class)
    .to('log:info');

I get the following error when integrtion is started.

As you are using JavaScript, you can't use convertBodyTo(String.class) as you would do in Java but you need to follow the graaljs interoperability guides, see https://github.com/graalvm/graaljs/blob/master/docs/user/JavaInterop.md#class-access
