Hi! When I follow Quickstart instructions, the backend exits with the following error. I realized this after login didn't work so #34 might also be related.

Thansk for pulling up this issue. Upon further investigation, it looks like the types.UnionType in the User(Base) model of app/app/models/user.py doesn't support the types.UnionType operation. The Base class is an odmantic.Model type and (issue ticket here) that is where the error is occurring. I'm putting up a fix to switch that back to Optional[int].
Fix: #42
Let me know if this resolves your issue.
