I had a very similar issue. I fixed it by replacing "passport.authenticate(strategy..." with "passport.authenticate('strategyName'...". |

Just came across this error while requesting data from multiple endpoints on page load. Thanks for sharing, this fixed my header error. Followed the steps from the original documentation (https://www.passportjs.org/concepts/authentication/strategies - #Register) and named my custom strategy first and then used the string for authenticate().

Hi,
I have issue with this code when testing using 2 simultaneous users (Playwright tests, using 2 workers) :
passport.authenticate(strategy, {}, { failureRedirect:/login, state: redirect_url }), (err, user, info) => { if (err || !user) { return next(err || info); } req.logIn(user, err => { if (err) { return next(err); } if (loginpopup) { ... } else { return res.redirect('/'); } }); })(req, res, next);I am receiving this error:
Error: Cannot set headers after they are sent to the client ...It seems to come from the "res.redirect('/')"
From various posts on stackoverflow, I kind of understand that the issue come from the fact that I do a redirect inside the "authenticate" callback and that redirect interfer with passport's redirect. But I don't know how to solve this.
Could you please help me understand and fix this issue ?
Thanks you
