@simaishi Looks like the back-port to the fine branch is breaking tests. Upstream we can dynamically create these automate service models if the class does not contain any logic. In this case we were removing the only line:
expose :manager, :association => true

But for back-porting we need to keep the empty models since they are not dynamically created.
