Resolution: Fixed
> camel-knative - add a muteException consumer option

> Key: CAMEL-24428
> URL: https://issues.apache.org/jira/browse/CAMEL-24428
> Project: Camel
> Issue Type: Improvement
> Components: camel-knative
> Reporter: Andrea Cosentino
> Assignee: Andrea Cosentino

> Fix For: 4.23.0

> CAMEL-23651 aligned the {{muteException}} consumer option so that a failed
> exchange does not return the exception's stack trace or message to the remote
> caller. The option exists in camel-http-common (and therefore camel-servlet
> and camel-jetty), camel-http, camel-netty-http, camel-platform-http and
> camel-undertow. A grep for {{muteException}} across {{components/}} still
> shows it in the http family only.
> {{KnativeHttpConsumer.computeResponseBody()}} returns the *full stack trace*
> of the route exception as the response body, unconditionally:
> {code:java}
> Exception exception = message.getExchange().getException();
> if (exception != null) {
> // we failed due an exception so print it as plain text
> final String stackTrace = ExceptionHelper.stackTraceToString(exception);
> // the body should then be the stacktrace
> body = stackTrace.getBytes(StandardCharsets.UTF_8);
> // force content type to be text/plain as that is what the stacktrace is
> message.setHeader(Exchange.CONTENT_TYPE, "text/plain");
> {code}
> Proposal: add a {{muteException}} consumer option, defaulting to {{true}} to
> match the post-CAMEL-23651 behaviour of the http family, with an
> upgrade-guide entry noting that routes relying on the detail must set it to
> {{false}} explicitly.
> *This issue was rescoped to camel-knative only.* The three other consumers it
> originally covered are now tracked separately so that each can be fixed and
> released on its own:
> * CAMEL-24476 - camel-mina
> * CAMEL-24477 - camel-cxf
> * CAMEL-24478 - camel-grpc
