content_object is not a Django model - manager.py:33

[DigitalOriginTech]

I'm reviewing DTA for use on an existing site. I'm currently stuck at a brick wall of an error that I don't believe has been discussed yet.

Django==3.2.9, DTA==1.1.1

--- Loading a view that's using ---
Tracker.objects.create_from_request(request, local_model_object)

--- Error ---
AssertionError at /account/
content_object is not a Django model

--- manager.py:33 ---
assert issubclass(content_object.class, models.Model)

Please let me know what else I can provide to help me get past this issue. I thank you in advance.
