passport js fails to maintain session when nodejs server restarts - node.js

Question

I am using nodejs, passportjs, jwtoken and mongoose to develop an application. I am facing some critical situation and stuck since 2 days.
I have used passport js for server side authentication and jwtoken for persistent login. It works very well ,with regular situation. But I have faced an issue before 3 days ago that when I restart server passport js fails to maintain session or expire nodejs user session. I don't know how to revalidate and recreate new passport session in nodejs.
I have tried a lot but failed to recreate. I found this issue when I tried to restart server and from web application any request sent to server. When I tried to access req.user to get user data from session it throws me req.user is undefined.
I even tried to use connect-mongo to store session but it throws an error -
"Error: failed to deserialize user out of session".
I don't know how to deal with situation. Provide me guidelines to resolve this issue.
Please refer below source code.
