How is the req object passed to Google callback?

I’ve only taken snippets of code from this repo for my project, but in

https://github.com/reactGo/reactGo/blob/master/server/db/sequelize/passport/google.js

for the Google OAuth2 strategy you can see there is a request object in the parameters: export default (req, accessToken, refreshToken, profile, done) => {...}

I couldn’t find where this was set or passed from. It must be somewhere in the middleware right? I was able to have access to the object after setting a passReqToCallback to be true here so it looks something like:

  passport.use(new GoogleStrategy({
    clientID: google.clientID,
    clientSecret: google.clientSecret,
    passReqToCallback: true,
    callbackURL: google.callbackURL
  }, handleGoogleUserInfo));

. Perhaps there can be some explanation on this in the docs or comments since this req object isn’t talked about in the raw Passport setup instructions? Thanks.

Thank you. @gsccheng I also think it needs passReqToCallback: true. I’ll make PR.
