Calling transformation function on receiver with Mono<Void> type
Reports transform operations called on Mono<Void> value inside a Reactor chain.
Mono<Void> completes without any value, that's why there is nothing to invoke the transformation function on. The quick-fix suggests replacing map() and flatMap() with then().
Locating this inspection
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
ReactorTransformationOnMonoVoid- Via Settings dialog
Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
Example:
Mono.when(Mono.just(1), Mono.just(2))
.map(v -> "New value")
.doFinally(System.out::println);
After the quick-fix is applied:
Mono.when(Mono.just(1), Mono.just(2))
.then(Mono.fromCallable(() -> "New value"))
.doFinally(System.out::println);
