express-jwt - typeError: done is not a function

Question

I'm using express-jwt to control the user privileges of my startup project, but I'm getting an error when I try to request access (using Postman) an api that only the admin can access. This is my authJwt document:

import { expressjwt } from "express-jwt";
import dotenv from 'dotenv';


dotenv.config();
const secretJwt = process.env.JWT_SECRET;

function authJwt() {
    return expressjwt({
        secret: secretJwt, 
        algorithms: ['HS256'], //https://jwt.io/
        isRevoked: isRevoked 
    })
    .unless({ 
        path: 
        [
            '/users/login',
            '/users/register',        
            { 
                url: /\/categories(.*)/, // (https://regex101.com/)
                methods: ['GET', 'OPTIONS'] 
            }
        ]
    })
}

async function isRevoked(req, payload, done) {
    if(!payload.isAdmin) {
        done(null, true)
    }
   done(); 
}

export default authJwt;

The error I'm getting is:

Answer 1

const {expressjwt: expressJwt} = require('express-jwt')

exports.authJwt = expressJwt ({ secret: secretJwt, algorithms: ['HS256'], //https://jwt.io/ isRevoked: isRevoked })....
