I'm running into an issue, which I think matches exactly what's being discussed here: expressjs/session#309.
REQ #1 > start processing /oauth/google/callback
REQ #1 > set user data to session
REQ #1 > issue redirect to /oauth/google/authenticated callback
REQ #1 > express-session intercepts redirect to wait for session to persist
browser already received redirect headers and issues the new request
REQ #2 > start processing /oauth/google/authenticated
REQ #2 > get user data from session, but nothing is found
REQ #2 > completed processing /oauth/google/authenticated with error
the other request is still being processed
REQ #1 > session persist completed
REQ #1 > express-session completes the redirect, i.e. closes the connection
REQ #1 > completed processing /oauth/google/callback
I'm not 100% sure this is exactly what's happening, but it looks like it. I will try to wrap grant's redirect in req.session.save(() => { res.redirect() }) to see if that helps, since I am generally able to reproduce this fairly easily.
