create_user is not getting called

I have a django application that uses django social auth to authenticate users with Google. It was working just fine and then....suddenly it stopped. I have no clue why. I've tried everything I can think of.

Here's my social auth pipeline:

SOCIAL_AUTH_PIPELINE = (
    'social_core.pipeline.social_auth.social_details',
    'social_core.pipeline.social_auth.social_uid',
    'myapp.custom_social_auth_pipeline.auth_allowed', 
    'social_core.pipeline.social_auth.social_user',
    'social_core.pipeline.user.get_username',
    'myapp.custom_social_auth_pipeline.create_user', <--- also tried with social auth's create user function
    'social_core.pipeline.social_auth.associate_user',
    'social_core.pipeline.social_auth.load_extra_data',
    'social_core.pipeline.user.user_details',
)

And here's the code on my custom_social_auth_pipeline:

from django.contrib.auth.models import Group, User
from django.shortcuts import redirect

USER_FIELDS = ['username', 'email']

def create_user(strategy, details, backend, user=None, *args, **kwargs):
    print("CREATE USER CALLED") <-- this is never called! :(
    if user:
        return {'is_new': False}

    fields = dict((name, kwargs.get(name, details.get(name)))
                  for name in backend.setting('USER_FIELDS', USER_FIELDS))

    try:
        if User.objects.get(email=fields['email']):
            return {'is_new': False, 'user': User.objects.get(email=fields['email'])}
    except:
        pass
    if not fields:
        return

    fields['is_staff'] = True
    user = strategy.create_user(**fields)
    staff = Group.objects.get(name='Staff')
    user.groups.add(staff)
    return {
        'is_new': True,
        'user': user
    }

def auth_allowed(backend, details, response, *args, **kwargs):
    print ("AUTH ALLOWED CALLED") <-- this prints in my logs
    print(details) <-- this returns the correct user
    if not backend.auth_allowed(response, details):
        return redirect('/')

It's not returning any error and it is not redirecting to our "error" url. It's just behaving like it does if no one is signed in (the app has a public-facing page that is for people who are not signed in, and if you try to go to another url, you get bounced back to that one). I feel like I must be missing something obvious, but I can't figure out what.

One other thing: it works perfectly on my local machine. On my server (AWS Lambda) it does not.

I'm just at a loss for what else to try, and would appreciate any guidance you can offer.

I just wanted to drop an update here. I figured out that I had updated some things, and the issue was that social-auth-core had upgraded to 4.1.0. After I downgraded this to 3.3.3, the problem resolved.

I only was able to figure this out because my coworker was able to push a build from her computer that worked, and so we compared our pip-freeze output.

No clue why it worked locally but not on our staging instance (AWS Lambda deployed via Zappa). I'm just putting this here so others can find it.
