[Flask] Issues with Flash_session - Cannot add dict item ..

[Ziirish]

Here is your problem:

from flask import session
session = Session()

The flask session object is not a Flask-Session Session object.

What you want instead is:


sess = Session()
sess.init_app(app)

Then you can do:

session['modified'] = False  # here session is the Flask's session object
