Obtenir une exception non livrable lors de l'utilisation completable

public Completable createBucketWithStorageClassAndLocation() {
        return Completable.complete()
                .doFinally(() -> {
            Bucket bucket =
                    storage.create(
                            BucketInfo.newBuilder(googleUploadObjectConfiguration.bucketName())
                                    .setStorageClass(storageClass)
                                    .setLocation(googleUploadObjectConfiguration.locationName())
                                    .build());       
        }).doOnError(error -> LOG.error(error.getMessage()));
    }

L'exception est lancée à partir du stockage Google qui est correct, mais essayant de gérer la méthode doOnError

Caused by: com.google.cloud.storage.StorageException: You already own this bucket. Please select another name.

De la documentation Rxjava https://github.com/reactivex/rxjava/wiki/What's-Different-in-2.0#Error-handling Je dois gérer l'erreur dans l'application.

J'ai besoin d'écrire le code ci-dessous,

/ If Java 8 lambdas are supported
RxJavaPlugins.setErrorHandler(e -> { });

Ma question est où devrais-je écrire ce code. J'ai une application Micronaut en utilisant Java ou c'est le seul moyen de gérer l'exception.

Utiliser Completable.fromAction Et peut-être essayer-attraper l'exception au lieu de ce doFinally Contraption:

Completable.fromAction(() -> {
    try {
        Bucket bucket = storage.create(
            BucketInfo.newBuilder(googleUploadObjectConfiguration.bucketName())
                      .setStorageClass(storageClass)
                      .setLocation(googleUploadObjectConfiguration.locationName())
                      .build()); 
    } catch (Throwable error) {
        LOG.error(error.getMessage());
    }
})
