Pasquale Congiusti commented on CAMEL-21599:
--------------------------------------------
I may contribute to the fix, but I'd need some direction to understand where
and when the global error handler is set in order to verify why it's not taking
effect.
> Global Error Handler does not take effect when a producer Kamelet fails
> -----------------------------------------------------------------------
>
> Key: CAMEL-21599
> URL: https://issues.apache.org/jira/browse/CAMEL-21599
> Project: Camel
> Issue Type: Bug
> Affects Versions: 4.9.0
> Reporter: Pasquale Congiusti
> Priority: Major
>
> I found a faulty behavior when configuring a global error handler and the
> failure is caused by the execution of a Kamelet.
> The following route works correctly:
> {code}
> - route:
> errorHandler:
> deadLetterChannel:
> deadLetterUri: kamelet:log-sink/errorHandler
> from:
> uri: timer:tick
> steps:
> - setBody:
> constant: "fail!"
> - setBody:
> simple: "${mandatoryBodyAs(Boolean)}"
> - log: "${body}"
> {code}
> It intercept the failing execution and forward the failure to the DLC.
> However, if the producer URI contains a failing Kamelet, then, the global
> error handler is not working. Wrapping the same failing logic in a local
> Kamelet like:
> {code}
> apiVersion: camel.apache.org/v1
> kind: Kamelet
> metadata:
> name: my-err-source
> labels:
