messages not appearing in admin on AWS dev server Django-3.1 - django

Question

context: Django 3.1 app deployed to a AWS lambda with terraform. I have not set up my production settings yet, this is my dev server.
I'm using https://github.com/adamchainz/apig-wsgi
I noticed that messages from django.contrib.messages don't appear when attempting to get the api key with djangorestframework-api-key via the admin. It being on the lambda means I'm unable to access the lambda REPL to create the api key programmatically.
note: django-debug-toolbar also does not work and does so quietly, so I have a sneaking suspicion my context_processors settings are off so I don't have messages or DEBUG variables but I can't find the issue in my settings?? Below is my code without debug toolbar settings.

default admin template admin/base.html where I'm expecting messages to show up (its just looping through the messages object, shouldn't need any JS or CSS to appear):

djangorestframework-api-key==2.1.0
attempts:
tried hard reload F5 and all that
tried adding django debug toolbar and logging the apikey that shows up in messages in the admin, but didn't work because toolbar also doesn't show up (not shown in code above)
tried collectstatic on dev server
tried checking user sessions and seeing the messages on user sessions and there are messages there

A talented colleague fixed this. Adding
MESSAGE_STORAGE = 'django.contrib.messages.storage.session.SessionStorage'
to your settings resolves the issue.
