title: express-session deprecated req.secret; provide secret option app.js:27:9
body: <p>I typed npm start to run my program but this is the comment that U received in the terminal: express-session deprecated req.secret; provide secret option app.js:27:9. I don't understand how this issue needs to be fixed.
  This is the code from app.js:27:9</p>
  <pre><code>app.use(session({
      store: new FileStore(),
      secret: process.env.SESSION_SECRET,
      resave: false,
      saveUninitialized: true,
      is_logged_in: false,
  }))
  </code></pre>
