Auth0 - jsonwebtoken verify - worker

Developers Workers
#1

Hello!

  1. I’m using the react auth0 provider to get an Auth0 token.
  2. I’m taking this TOKEN and passing it via url param (as a test for now, eventually it would be a header) and try to decode it using jsonwebtoken verify function
  3. The token is not getting verified.

This is my code (I’m setting type = “webpack” in my wrangler.toml so I can import modules):

import { verify } from 'jsonwebtoken'

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request))
})

async function handleRequest(request) {
  const url = new URL(request.url)
  const { searchParams } = url
  let token = searchParams.get('token')

  if (url.pathname === '/auth') {
    try {
      verify(
        token,
        STRING_SECRET,
        { algorithms: ['RS256'] },
        function(err, payload) {
          console.log('payload', err, payload)
        },
      )
    } catch (err) {
      console.log('error decoding', err.message, err.name)
    }
  }

  return new Response('No response', {
    headers: { 'content-type': 'text/plain' },
  })
}

The console.log(‘payload’, err, payload) is not showing an err or a payload. This is what the Cloudflare logs are showing:

"logs": [
    {
      "message": [
        "payload",
        {},
        null
      ],
      "level": "log",
      "timestamp": 1654695913617
    }
  ],

How can I verify this token? Appreciate any ideas.

Thank you!
