(Apologies if this is not be the right place for this report; this is just an educated guess from the backtrace.)

Consider this simple app (which started life as the flask_migrate trivial example):

#!/bin/env python3

from flask import Flask, g, render_template
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager, current_user, UserMixin
# from flask_migrate import Migrate
from config import Config  # SECRET_KEY, SOCIAL_AUTH_GOOGLE_OAUTH2_KEY, SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET are in here

from social_flask.routes import social_auth
from social_flask_sqlalchemy.models import init_social

app = Flask(__name__)
login_manager = LoginManager()
# migrate = Migrate()

app.register_blueprint(social_auth)
app.config["SOCIAL_AUTH_USER_MODEL"] = "app.User"
app.config["SQLALCHEMY_DATABASE_URI"] = "sqlite:///db.sqlite"
app.config["SOCIAL_AUTH_AUTHENTICATION_BACKENDS"] = ("social_core.backends.google.GoogleOAuth2",)
app.config.from_object(Config)
db = SQLAlchemy(app)
login_manager.init_app(app)


class User(UserMixin, db.Model):
    __tablename__ = "users"
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(64), index=True, unique=True)

    def __repr__(self):
        return '<User {}>'.format(self.username)


def init_app():
    init_social(app, db)  # User needs to be defined before here
    # migrate.init_app(app, db)
    print(f"app initialised")


@login_manager.user_loader
def load_user(userid):
    return User.query.get(int(userid))


@app.before_request
def global_user():
    # evaluate proxy value
    g.user = current_user._get_current_object()


@app.context_processor
def inject_user():
    """ make g.user available (as 'user') to templates """
    try:
        return {"user": g.user}
    except AttributeError:
        return {"user": "nope"}


@app.route('/')
def index():
    return render_template('index.html')


if __name__ == "__main__":
    init_app()
    app.run(host="127.0.0.1", port=8080, debug=True)

For completeness, the index.html template:

<!doctype html>
<html>
    <head><title>Test</title></head>
    <body>
        {% if user.is_authenticated %}
            Logged in as {{ user.username }}!
        {% else %}
            Not logged in - go <a href="{{ url_for('social.auth', backend='google-oauth2') }}">here</a>!
        {% endif %}
  </body>
</html>

The app mostly works...but while processing social.complete (returning from google, in this particular case):

TypeError: 'module' object is not callable

I've tried to look very carefully for a dumb error at my end, but I can't for the life of me work it out.

Relevant module versions (these are all the latest available versions):
Flask==2.3.3
Flask-Login==0.6.2
Flask-SQLAlchemy==3.1.1
social-auth-app-flask==1.0.0
social-auth-app-flask-sqlalchemy==1.0.1
social-auth-core==4.4.2
social-auth-storage-sqlalchemy==1.1.0
SQLAlchemy==2.0.20
