> The [Olingo4Consumer|https://github.com/apache/camel/blob/master/components/camel-olingo4/camel-olingo4-component/src/main/java/org/apache/camel/component/olingo4/Olingo4Consumer.java#L102] when filtered using the already-seen property, is checked for empty EntitySets and returns 0. This return value ensures that unless consumer.sendEmptyMessageWhenIdle = true, no empty messages are generated.
> However, this behaviour is not consistent when a key predicate is used. In this case, an entity is returned which is then filtered to null. This is not handled and an empty message is transmitted with a null body.
