Couchbase Document Expiry isn't working with spring-data-couchbase:.4.0.3.RELEASE

Question

Tried setting expiry to 60 seconds on a document as mentioned in below reference document with spring-data-couchbase-4.0.3.RELEASE lib. However, the expiry doesn't work as resets the value to 0.

spring-data-couchbase reference document

I have found that the value is being reset to 0 in ReactiveUpsertByIdOperationSupport class file in below method.

private UpsertOptions buildUpsertOptions() {
    final UpsertOptions options = UpsertOptions.upsertOptions();
    if (persistTo != PersistTo.NONE || replicateTo != ReplicateTo.NONE) {
        options.durability(persistTo, replicateTo);
    } else if (durabilityLevel != DurabilityLevel.NONE) {
        options.durability(durabilityLevel);
    }
    return options;
}

Not sure how I can fix this issue. Any help is appreciated. Thanks,
