Hey @TylerRudie, thank you for reporting this. I'm not using Oracle personally; however, from the stack trace that you provided, it seems clear what the problem may be. Could you please try a version with the fix from the master branch?
pip3 install git+https://github.com/ivelum/djangoql.git@534b52938b65b63a8c4ff7b5d5355c5f2aa03781
If it works for you, I'll push a bugfix release to PyPI.
