Here, we really expect an `IEnumerable` and should always get one based on the format of the data we're getting from the server, but the same method is called in other places for other formats. In some places, an `int` is expected as the return type for example. This isn't really nice and a bit confusing which is why we should probably clean this up, but I would rather do that with a separate PR as it's really not related to this PR. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
