If you sync a repo with an errata that does not have a package list such as this one here:

https://github.com/Katello/runcible/blob/master/test/fixtures/repositories/zoo5/updateinfo.xml#L3-L9

and then try to generate applicability for a consumer, you will get an error:

This used to work (on at least 2.8.7), but no longer does on 2.9.3 an newer.
