How to get user details using passport-SAML in node js

Question

I'm using passport-SAML in node js for SAML authentication. my SAML Saml Strategy

passport.use(new SamlStrategy({
    protocol: 'https://',
    entryPoint: 'https://accounts.google.com/o/saml2/idp?idpid=', // SSO URL (Step 2)
    issuer: 'https://.../sp', // Entity ID (Step 4)
    path: '/auth/saml/callback' // ACS URL path (Step 4),
    cert:"fake certificate"

  }, function (profile, done) {
    // Parse user profile data
    done(null, {
      email: profile.email,
      name: profile.name
    })
  })
)

And my login code

app.get('/login', passport.authenticate('saml', {
  successRedirect: '/',
  failureRedirect: '/login'
}))

I have cloned project from Git hub

I'm not able to get user details and also not able to print any console log in '/login' route. How I can achieve this?
