problem of the method language with filter pattern

[cristph]

I'm using camel-karavan to delpoy my camel.yaml integration, code as below:

- route:
    from:
      uri: direct:test11
      steps:
        - filter:
            expression:
              method:
                ref: testCheck
                method: check
            steps:
              - bean:
                  ref: testCheck
                  method: check
                  beanType: com.test.TestCheck
    id: test11

and testCheck is a Spring Bean

@Component("testCheck")
public class TestCheck {

    @Handler
    public boolean check() {
        return true;
    }

}

when loading the route, I encountered the following problem:

org.apache.camel.FailedToCreateRouteException: Failed to create route test11 at: >>> Filter[bean[ref:testCheck method:check] -> [Bean[ref:testCheck method:check]]] <<< in route: Route(test11)[From[direct:test11] -> [Filter[bean[ref:testCh... because of NullPointerException

It seems like that the method language does not work with the filter pattern, anyone can help? much appreciated!

camel-springboot: 3.18.4
camel-karavan: the latest 3.18.6

Yeah it seems like a bug in camel-core / yaml-dsl. I created a ticket https://issues.apache.org/jira/browse/CAMEL-18807

[davsclaus]

Okay the bug is fixed and will be in next releases 3.18.5 and 3.20.0

You can configure karavan to what Camel version it should use, so when 3.20.0 is out you can use that, or wait for 3.18.5 etc.

And please if you find other issues then you are very welcome to report here
