This looks like the same mistake I made when doing metrics for publishing-api:
We need to explicitly require the push library to use it. I'm not 100% sure if we really need the other two imports (client and registry), but publishing-api has them, so we may as well be consistent. Can't hurt, surely.
Follow these steps if you are doing a Rails upgrade.
