Answer 1

If you are using jsonwebtoken lib, I tried and able to create the token and verify as well. Please have a look at the code and let me know in comments if you are still facing the issue.

var jwt = require('jsonwebtoken')

const secret = 'secret';
const token = jwt.sign({
        username: "",
        userID: 1
    },
    secret, {
        expiresIn: "1hr"
    },
    function(err, token) {
        if (err) {
            console.log(err);
        } else {
            console.log(token);
        }
    });

Here is the link of jwt.io where I entered your secret used and it's saying verified.
