RequestLifecycle onErrorNoFilter default logging MDC propagation

[andrew-pirkl]

Hey all, I have a question about the RequestLifecycle and the way default error handling works. When a request goes through the onErrorNoFilter function and has no errorRoute or ExceptionHandler defined, then the exception eventually logged through the call to createDefaultErrorResponseFlow doesn't include the PropagatedContext and so doesn't include any of the propagated MDC items.

Is this by design, and is there a suggested way to make the MDC items available in that log? I tried creating a generic ExceptionHandler to handle all exceptions and log it there so it goes through handlerExceptionHandler and that correctly includes the MDC items in the logged exception, but I'd prefer to not have to have that custom handler.

I did see there was a related bug fixed here: #11847
