ReactPy websocket authentication has failed!

[numpde]

I'm using 'allauth' in my Django project. While loading a 'Hello world' component from a template (which does show up on the page), I get the following error. There are many moving parts, so please let me know what other details you might need.

ValueError: You have multiple authentication backends configured and therefore must provide the `backend` argument or set the `backend` attribute on the user.

# In settings.py:
AUTHENTICATION_BACKENDS = [
    # Needed to login by username in Django admin, regardless of `allauth`

Using:

reactpy==1.0.1
reactpy-django==3.1.0

@Archmonger, perhaps related to #151?

[Archmonger]

Yup, same issue.

Resolved via this PR, will be released as v3.2.0 shortly.

You will need to define REACTPY_AUTH_BACKEND assuming that...

1. You are using AuthMiddlewareStack and...
2. You are using Django's AUTHENTICATION_BACKENDS setting and...
3. Your Django user model does not define a backend attribute

Affirmative. Thanks!
