Here's what you should Alternatively it would be enough (and more general) if we had a "defer" variant for switchIfEmpty which would take a Supplier<Mono> similar to defer(). On the other hand, . If you That means that calling a method returning such a Flux to capture it in switchIfEmpty isn't that much of a problem. The behavior is identical, but the latter is more Why does the entire operation just hang if I add the switchIfEmpty operation? It doesn't matter if I use flatMap instead of concatMap, it will hang eventually anyways. just, most Mono objects/implementations are Reactor comes with a few elements dedicated to testing, gathered into their own artifact: reactor-test. 2 Can we handle more than one exception with switchIfEmpty in Reactor?
