Why do I get error JwtStrategy requires a secret or key?


I get this error “TypeError: JwtStrategy requires a secret or key” and I can’t figure out how to fix it. What can I do to fix it?

(node:46218) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 exit listeners added to [Bus]. Use emitter.setMaxListeners() to increase limit
        throw new TypeError('JwtStrategy requires a secret or key');

What I have tried

  • renaming the varable opts
  • checked so the variables are named the same
  • tried using dotenv
  • replacing keys.secretOrKey with a string


const JwtStrategy = require('passport-jwt').Strategy;
const ExtractJwt = require('passport-jwt').ExtractJwt;
const mongoose = require('mongoose');
const User = mongoose.model("users");
const keys = require("./keys")

const opts = {};

opts.jwtFromRequest = ExtractJwt.fromAuthHeaderAsBearerToken();
opts.secretKey = keys.secretOrKey;

module.exports = passport => {
        new JwtStrategy(opts, (jwt_payload, done) => {
            .then(user => {
                if (user) {
                    return done(null, user)
                return done(null, false)
            .catch(err => {


module.exports = {
    secretOrKey: 'secret'


You have to use right key name for secretkey in options. You should write like this:-

opts.secretOrKey = keys.secretOrKey

By mistake you wrote opts.secretKey.
Hope this helps!
