ValueError: too many values to unpack (expected 2) in Django

I am reorganizing one of my projects to be more re-usable and just generally structured better and am now getting the error below whenever I run

- I've spent half the day trying to figure this out on my own but have run out of Google results on searches and am in need of some assistance. What I've done was remove a custom user model I had setup so I can use Django's built-in User model and I also namespaced my apps urls. I don't want to include a bunch of code yet that will do nothing but dirty up this post as I am hoping the Traceback has clues that I am not seeing. If you are looking at this and have an idea of what could be the culprit for the error, can you please advice on what you need to see to offer assistance? Thank you.

This error would only occur if split() returns more than 2 elements:

app_label, model_name = model.split(".")
ValueError: too many values to unpack (expected 2)

This means that either app_label or model_name has a dot (.) in it. My money is on the former as model names are automatically generated
