Passport that authenticating user - node.js

Question

I have the following code
passport.authenticate("local", (err, token, user) => {
if (err) {
console.dir('test4');
console.dir(err);
return res.json({
status: "error",
error: "Invalid user.",
});
}
console.dir(token);
if (!user) {
console.dir('test5');
return res.json({
status: "error",
error: "Invalid user.",
});
} else {
req.logIn(user, (err) => {
if (err) {
console.dir('test6');
console.dir(err);
return res.json({
status: "error",
error: "Invalid user.",
});
}
res.clearCookie("auth");
res.cookie("auth", token);
req.session.user = result;
return res.json({
status: "ok",
result: {
token,
user
}
});
});
}
})(req, res, next);
})
.catch((err) => {
console.dir(err);
return res.json({
status: "error",
error: _.isObject(err) ? "There was an error processing your request. Please try again later." : err,
});
});
I'm not able to authenticate the user using passport. Here's my passportConfig
const User = require("./models/user");
const LocalStrategy = require("passport-local").Strategy;
const jwt = require('jsonwebtoken');
module.exports = function (passport) {
passport.use(
new LocalStrategy((username, password, done) => {
User.login(username, password).then(result => {
const payload = {
sub: result[0].id
};
// create a token string
const token = jwt.sign(payload, process.env.JWT_SECRET);
return done(null, token, result[0]);
}).catch(err => {
return done(null, false);
});
})
);
passport.serializeUser((user, cb) => {
cb(null, user.id);
});
passport.deserializeUser((id, cb) => {
console.dir('test33');
console.dir(id);
User.fetchByEmail(id).then(result => {
cb(null, result[0]);
}).catch(err => {
cb(err, null);
});
});
};
and here's my index.js
app.use (
session ({
secret: "x",
resave: false,
saveUninitialized: true,
// proxy: true,
// rolling: true,
cookie: {
expires: new Date(Date.now() + (60*60*1000*24*90)),
secure: true
}
})
);
app.use(cookieParser());
app.use(passport.initialize());
app.use(passport.session());
require("./passportConfig")(passport);
what I'm I doing wrong?
The code brings out "test5".
