Hi Claus, Thank you very much for the quick response. I assumed that one could use the dead letter channel as a workaround, but logically I thought it should be possible simply to set the logName or the loggerRef on the DefaultErrorHandler like it was the case with the LoggerErrorHandler. Hence my question. Could that be readed as a feature in the future? The dead letter channel solves my issue for now. Thanks again.

That is essentially what the log error handler did. https://camel.apache.org/manual/error-handler.html On Fri, Nov 25, 2022 at 2:01 PM Tasi, Erne <e.t...@cenit.com.invalid> wrote: > Hello All, > > We are using Camel in Karaf and recently we upgraded Karaf to version > 4.2.1 and camel to 3.18.3.
