Been trying to fix this for a few days now.

Exchange an OAuth2 access token for one for this site.
This simply defers the entire OAuth2 process to the front end.
The front end becomes responsible for handling the entirety of the
OAuth2 process; we just step in at the end and use the access token
to populate some user identity.
The URL at which this view lives must include a backend field, like:
url(API_ROOT + r'social/(?P<backend>[^/]+)/$', exchange_token),
Using that example, you could call this endpoint using i.e.
POST API_ROOT + 'social/facebook/'
POST API_ROOT + 'social/google-oauth2/'
Note that those endpoint examples are verbatim according to the
PSA backends which we configured in settings.py. If you wish to enable
other social authentication backends, they'll get their own endpoints
automatically according to PSA.

Requests must include the following field

This is the line it refers to in the traceback:

I've verified my ReactJS FE is correctly sending the access_token as I can print it out server-side with print(request.data) and print(serializer.validated_data['access_token']). Everything seems to be flowing properly until it gets to verifying the access_token server-side at:
user = request.backend.do_auth(
serializer.validated_data['access_token'])
The user it is trying to validate should not be in the database currently, if that helps.
Suggestions for what I'm doing wrong here or how to resolve it?
I think its supposed to be
serializer.is_valid(raise_exception=True)
serializer.data
Try changing this line user = request.backend.do_auth( serializer.validated_data['access_token'])
with
user = backend.do_auth( access_token, response={"id_token": id_token}) #Id token you will get along with access token.
