Passport authentication with JWTStrategy not working - Error: Could not get a response

Hello, I was trying to authenticate with passport JWTStrategy

passport-oauth.js :

const passport = require('passport');
const JwtStrategy = require('passport-jwt').Strategy,
    ExtractJwt = require('passport-jwt').ExtractJwt;

const oauth = require('../oauth/oauth_credentials');
const User = require('../models/user');

var opts = {};
opts.jwtFromRequest = ExtractJwt.fromAuthHeaderAsBearerToken();
opts.secretOrKey = require('./jwt').secret;

console.log('Obviously control comes here');
passport.use(new JwtStrategy(opts, function (jwt_payload, done) {
    console.log('Control never comes here');
    User.findOne({ _id: jwt_payload.sub }, function (err, user) {
        if (err) {
            return done(err, false);
        }
        if (user) {
            return done(null, user);
        } else {
            return done(null, false);
        }
    });
}));

passport.serializeUser(function (user, done) {
    done(null, user._id);
});

If you see my two console.log() functions, the control never comes to passport.use(new JWTStrategy…

I am authenticating here :

router.post('/test', passport.authenticate('jwt', { session: false }), (req, res) => {
    res.send('Authenticated');
});

I used postman to send my request :

As you can see I provided the authentication header too , and I am getting this error Could not get a response . If anyone could please tell me what’s wrong, I’ve been at it since hours.

Thanks.

hey guys, i had the same problem and solved the problem by writing a little middleware

// passport.js
passport.use(new JWTStrategy({
    jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
    secretOrKey: process.env.SERVERSECRET
}, (token, done) => {
    return done(null, token);
}));

// router/index.js

/**
 * middleware for checking authorization with jwt
 */
function authorized(request, response, next) {
    passport.authenticate('jwt', { session: false, }, async (error, token) => {
        if (error || !token) {
            response.status(401).json({ message: 'Unauthorized' });
        } 
        try {
            const user = await User.findOne({
                where: { id: token.id },
            });
            request.user = user;
        } catch (error) {
            next(error);
        }
        next();
    })(request, response, next);   
}

router.use('/user', authorized, userRouter);

// router/user.js

router.get('/', (request, response, next) => {
    response.send(request.user);
});

and in my request i had to set Authorization: bearer <token>

I assume your console.log(jwtPayload) is not printing anything ?
