I'm receiving error Error: req#logout requires a callback function when trying to log out of my app.
The issue is due to a passport.js update (from 0.5.3 to 0.6.0) which removed a vulnerability and there are several documented fixes on stack but even after adding a callback to my logout function (in app.js below), I'm still receiving an error response.
- Error! Your request cannot be completed. Please validate your information and resubmit.`
I recently removed high-risk vulnerabilities which is what I'm thinking created this issue because logout was working a few weeks ago.
app.js
const passport = require('passport');
app.use(passport.initialize());
app.use(passport.session());
passport.use(new LocalStrategy(User.authenticate()));
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());
app.use((req, res, next) => {
res.locals.currentUser = req.user;
res.locals.success = req.flash('success');
res.locals.error = req.flash('error');
next();
})
app.get('/login', (req, res) => {
res.render('users/login');
})
app.post('/logout', function(req, res, next) {
req.logout(function(err) {
if (err) { return next(err); }
res.redirect('/');
});
});
client side code
<a class="dropdown-item fs-5" href="/logout">Logout</a>
I've tried console logging the error within the error handler but I can't get any additional detail as to what's happening. How do I fix my logout?
