----------------------------------------
Summary: camel-coap - add a muteException consumer option
Key: CAMEL-25087
URL: https://issues.apache.org/jira/browse/CAMEL-25087
Project: Camel
Issue Type: Improvement
Components: camel-coap
Reporter: Andrea Cosentino
Fix For: 4.18.5, 4.23.0, 4.22.2
CAMEL-23651, and then CAMEL-24428, CAMEL-24476, CAMEL-24477 and CAMEL-24478,
gave the consumers that reply to the caller a {{muteException}} option
defaulting to {{true}}, so that a failed exchange does not return the
exception's message to the remote caller. camel-coap has no such option.
{{CamelCoapResource.handleRequest}} differs from those consumers in two places:
# After {{consumer.getProcessor().process(camelExchange)}} it does not check
{{camelExchange.isFailed()}}, so a failed exchange is answered with {{2.05
Content}} and whatever body the message held when the route failed.
# An exception raised while the consumer builds the response, for example
converting the final body to {{byte[]}}, is caught and its message is sent back
as the {{5.00}} payload:
{code:java}
} catch (Exception e) {
cexchange.respond(ResponseCode.INTERNAL_SERVER_ERROR, e.getMessage());
}
{code}
Proposal: add a {{muteException}} consumer option, defaulting to {{true}} to
match the other consumers. Answer a failed exchange with {{5.00 Internal Server
Error}}, with an empty payload when muted and the exception message when
{{muteException=false}}, and apply the same rule in the catch block. Add an
upgrade-guide entry for both changes.
