Updating data in Okta portal is overwritten if user is logged in

[atrp]

Example: If we update a custom field in Okta and logout out from our application and log back in the data we previously saved in Okta is replaced by the data stored in the users's session even though they logged out.

We do want to update a custom filed when we login (but apparently it updates all custom data which also has the previous data stored in the session).

    postLoginHandler: function(acct, req, res, next) {
        acct.customData.lastLogin = moment().tz('America/Chicago').format('YYYY-MM-DD');
        acct.customData.save();
        next();
    },
