Flask-Session session not saving inside a Flask-SocketIO websocket request

Question

I am using Flask-Session with Flask-SocketIO, but when I try to save my session from inside a websocket, it does not store, even though I am using server side session storage. I am redirecting the user directly after the session is stored.

session['li'] = True
session['id'] = account['id']
session.modified = True

Flask 2.2.2
Flask-Session 0.4.0
Flask-SocketIO 5.3.0

Answer 1

Well, I found a solution by adding a random key-value pair to the session when the login page was opened.
