What changed?
The registration for each ingester controller requires the GVK from each CRD and then a controller named ingester_<GVK> is registered. However, the GVK is not set by default and hence obj.GetObjectKind().GroupVersionKind() returns empty hence an ingester-controller with the name ingester_ is attempted to be registered. Therefore we encounter the following error in the second ingester-controller registration:

controller with name ingester_ already exists. Controller names must be unique to avoid multiple controllers reporting to the same metric

How did you test it?
Ran sandbox against changes. All ingester controllers were registered:
