As you can see in the NodeJS code I'm grabbing the user from the token from Postman provided in the URL but I'm struggling to get back the _id property from the given token number. What I want is that id in the decoded._id so that I can use that id in further operations

const jwt = require('jsonwebtoken')
const User = require('../model/users')
const auth = async (req, res, next) => {
    try {
          const token = req.header('Authorization').replace('Bearer', '')
          const decoded = jwt.verify(token, 'thisisfromabhishek')

`the property _id does not exist on decoded`
          const user = await User.findOne({ _id: decoded._id, 'tokens.token': token })

        if (!user) {
            throw new Error()
        }
        req.token = token
        req.user = user
        next()
       } catch (e) {
        res.status(401).send({ error: 'Please authenticate.' })
    }
}

module.exports = auth

Typescript don't know about _id in token. Data declaration should help.

interface JwtPayload {
  _id: string
}

const { _id } = jwt.verify(token, 'thisisfromabhishek') as JwtPayload

req.user = await User.findOne({ _id, 'tokens.token': token })

you have not given space after Bearer.

const token = req.header('Authorization').replace('Bearer', '') //here is the problem place space after Bearer
          const decoded = jwt.verify(token, 'thisisfromabhishek')

Typescript don't know about _id in token, add JwtPayloqd type or interface with id

interface JwtPayload {
    id: string;
}

const decoded = jwt.verify(token, process.env.JWT_SECRET!) as JwtPayload;
console.log(decoded);
