Property '_id' does not exist on type 'string | JwtPayload'. Property '_id' does not exist on type 'string'

Question

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

it not showing me any error in console its just not grabbing the _id property some autocomplete from the editor but because of that I'm not able to grab _id — Abhishek Vats, Oct 07 '21 at 13:18
"tokens" : [ { "token" : "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJfaWQiOiI2MTVlZWY1MmM4NTZlYmFkMTM3NTIzNjIiLCJpYXQiOjE2MzM2MTE2MDJ9.13oo0gCXb_fGyElG4g3Uakf2g7LGdih6fV5pHOK6vkI", "_id" : ObjectId("615eef52c856ebad13752364") } ] — Abhishek Vats, Oct 07 '21 at 14:00
so your token is stored in a JSON. What is the exact value of `token` that you pass to `jwt.verify(token...`? It should be only the token itself, `eyJhb.....` — jps, Oct 07 '21 at 14:31
this value of token passing in "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJfaWQiOiI2MTVlZWY1MmM4NTZlYmFkMTM3NTIzNjIiLCJpYXQiOjE2MzM2MTE2MDJ9.13oo0gCXb_fGyElG4g3Uakf2g7LGdih6fV5pHOK6vkI" in Postman headers in Authorization key — Abhishek Vats, Oct 07 '21 at 14:52
if you have a string "Bearer eyJhbGciOiJIUz..." and then just remove the word "Bearer", you still have a blank in front of the token, e.g. " eyJhbGciOiJIUz..." . Could this be the problem? — jps, Oct 07 '21 at 15:26
I did tried that after your recommendation but still I'm not getting the desired result I think its of the _id only because it's still showing me the same and it's getting the _id — Abhishek Vats, Oct 08 '21 at 13:16

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);

Your answer could be improved by adding more information on what the code does and how it helps the OP. – Tyler2P Sep 18 '22 at 17:53

Property '_id' does not exist on type 'string | JwtPayload'. Property '_id' does not exist on type 'string'
