I could reproduce this issue locally, and this is what I believe is happening with this environment (and not for other upgrades) is that the database has no domains defined for the interfaces related, so this piece of code [0] is falling into the "else" section which calls get_default_domain() method and internally ends up query the 'ttl' column. So the migration step 0011 is relying on it and expecting that it was created in step 0010 and it wasn't, it was added way later in migration step 0023.
