Problem with LeakLooker, macOS

[mayhem78]

So I have this error when trying to run a search with LeakLooker:

I tried to recreate the issue but I couldn't. However this are the steps I take when something goes wrong.

1. Delete sql3 file and everything from "migrations" directory except "init.py". Make sure that redis and celery is running as root and there was no problem during database migrations.
2. Create a new virtual environment. I use pycharm - https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html
