How to reproduce

Even deletion of db.sqlite3 and migration doesn't fix it.

• Deleted db.sqlite3
• Run ./manage.py migrate
• Start up the local development server and ngrok forward to it.
• run a /penny chat and invite one user and post in 2 channels and get the error

Still trying to figure out what is going on, but here's one sqlite3 db file that was giving me issues:

db.zip

The penny chats I tried seem to have been saved to the database:

Not a bug, needs to run ./manage.py background_tasks during development to get /penny chat to work.
