Cannot register classes from a submodule import

Consider the following project structure:

demo
├── bo.py
├── settings.py
└── sub
    └── bo.py

settings.py

import bo
import sub.bo

CLASSES = {
    'demo.bo.MyOperation': bo.MyOperation, # working
    'demo.sub.MySubOperation': sub.bo.MySubOperation, # not working
    'demo.sub.MySubOperation2': { # working alternative
        'module': 'bo',
        'class': 'MySubOperation',
        'path': '/irisdev/app/src/python/demo/sub'
    },
}

When trying to run iop migrate I encounter the following error:

irisowner@f2218db55070:/irisdev/app$ iop -m src/python/demo/settings.py
