What would be the error with this token verification code? - node.js

Question

When making the middleware request in my route, I always fall into the else of "verifyAdmin" (error 403). The big problem is that I can't send a throw or catch of this error, it just doesn't return any error in the terminal, but when testing in postman it always goes to else
const jwt = require('jsonwebtoken');
const verifyToken = (req, res, next) => {
const { authorization } = req.headers;
if (!authorization) {
return res.status(401).json('Invalid Authorization')
};
const token = authorization.replace('Bearer', ' ').trim();
try {
const secret = process.env.JWT_SECRET;
const data = jwt.verify(token, secret);
req.users = data;
const { id } = data;
req.userId = id;
return next();
} catch (err) {
return res.status(400).json(err);
}
};
const verifyAdmin = (req, res, next) => {
if (req.users.isAdmin === true) {
next();
} else {
return res.status(403).json("You are not alowed to do that!");
}
};
module.exports = {
verifyToken,
verifyAdmin,
};
in route
const { verifyToken, verifyAdmin } = require('../middlewares/verifyToken');
router.get('/', verifyToken, verifyAdmin, FindAllUsersController.index);
construction token
const db = require('../../models/index');
const bcrypt = require('bcryptjs');
const jwt = require('jsonwebtoken');
exports.store = async (req, res) => {
const { email, password } = req.body;
const secret = process.env.JWT_SECRET;
try {
const user = await db.User.findOne({ where: { email } });
if (!user) {
return res.status(401).json('User does not exist');
}
const isValidPassword = await bcrypt.compare(password, user.password);
if (!isValidPassword) {
return res.status(401).json('Password is not valid');
}
const token = jwt.sign({ id: user.id }, secret, {
expiresIn: process.env.EXPIRES_TOKEN,
})
return res.status(200).json({
user,
token,
});
} catch (err) {
console.log(err);
}
}

The isAdmin flag is not contained in your token, because you include only the id when constructing it:
const token = jwt.sign({ id: user.id }, ...)
You need (at least):
const token = jwt.sign({ id: user.id, isAdmin: user.isAdmin }, ...)
