I've been trying all night to get this stack to start up. I'm using Docker with the latest image. All of the containers start, except the backend.
This is the error I get, regardless of what I do.

TypeError: 'NoneType' object is not iterable
ERROR:    Application startup failed. Exiting.
Backend startup event
INFO:     Started server process [1]
INFO:     Waiting for application startup.
ERROR:    Traceback (most recent call last):

Any idea what is going on?
