reactive error handling

[pietermartin]

Is it possible to have the error handling go via reactive's doOnError
Already doOnComplete fires but doOnError is swallowed.
Seems to me the only way to get the StateMachineEventResult is to block.

StateMachineEventResult<String, String> result = activityRecord.triggerHandleSignal()
    .subscribeOn(ICmStateMachine.TRIGGER_THREADS)
    .doOnComplete(() -> {
    })
    .doOnError(throwable -> {
    })
    .blockLast();

Would it not be better if the exception propogates to doOnError?

Thanks
