I ran into that issue:

• I cannot get the access the session object in the request object inside the apollo server context, so I get undefined as output.
• Otherwise I can access the session object in the request object inside express routes as normal.

How can I solve that?

import express, { Application, Request, Response } from 'express';
import bodyParser from "body-parser"; 
import helmet from "helmet";
import xss from 'xss';
import moment from "moment";
import passport from "passport";
import { connect } from "mongoose";
import "reflect-metadata";
import { ApolloServer } from 'apollo-server-express';
import { buildSchema, ResolverData } from "type-graphql";
// Import resolvers
import main_config from './main.config';
import AuthenticationRoutes from './Authentication/Authentication.routes';
import './Authentication/Authentication.strategies';
import { 
    topicResolver, docsResolver, courseResolver, articleResolver, projectIdeaResolver 
} from './Graphql/Topics/Topics.resolvers';
import cookieSession from 'cookie-session';
import expressSession from 'express-session';
// const expGql = require("express-graphql");

const app : Application = express();

// Init cookie cookie-session
app.use(cookieSession({
    keys : ["IDFVBHNIOVFFBUE"],
    name : 'DBDIUN',
    secret : "IDFVBHNIOVFFBUE"
}));

async function runapp (){
    // Ïnit passport app and routes
    app.use(passport.initialize());
    app.use(passport.session())

    // Run apollo server 
    const apollo = new ApolloServer({
        schema : await buildSchema({
            resolvers : [
                topicResolver, docsResolver, courseResolver, articleResolver, projectIdeaResolver
            ],
            globalMiddlewares: [],
        }),
        context: ({ req, res }) =>{
            console.log("context")
            console.log(req.session.passport) // cannot get session object then Get undefined 

            return {
                getUser: () => req.user,
                logout: () => req.logout(),
            }
        },
        playground : true
    })
    apollo.applyMiddleware({ app });

    // Init body parser and helmet 
    app.use(helmet());
    app.use(bodyParser.json());

    app.use('/auth', AuthenticationRoutes)

}
runapp();
