How to throw another exception in Mono?

Question

I try to wrap exception that thrown in Mono into another exception. I try to use onErrorResume() and doOnError() methods, but it does not help. How can I do it?

 return response
                .handle((responseData, sink) -> handleStatus(data, logContext, sink))
                .doOnError(v -> {
                    throw new CriticalException("str", "str", "str", "str", "str", "str");
                });

Ok, and why does it not work? Is `CriticalException` a checked exception? — tquadrat, Jun 04 '21 at 13:30

Ideally use onErrorResume(), resuming to a publisher that supplies your new error as so:

.onErrorResume(e -> Mono.error(new CriticalException()))
