[Bug] TypeError: Illegal invocation

[togmund]

Hey!

I'm running into:

Uncaught (in promise)
TypeError: Illegal invocation
    at worker.js:1:5254
    at f (worker.js:1:3637)
    at Object.run (worker.js:1:4646)
    at worker.js:1:4769
Uncaught (in response)
TypeError: Illegal invocation

When trying to use req.body.text() and req.body.json() in a cloudflare worker.
I've wrapped the invocation in a try/catch and the error is empty.

With Worktop

import { Router } from 'worktop'
const API = new Router()

API.add('POST', '/webhook', async function (req, res) {
    const body = await req.body.text()
    console.log(body)
})

addEventListener('fetch', API.listen)
// TypeError: Illegal invocation

Without Worktop

async function handleRequest (request) {
  const body = await request.text()
  console.log(body)
}

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

Hey, thanks! Fixing now – sorry about that :)

Your request should have the appropriate Content-Type header anyway, so until the next release goes out (in the next day or two!), you should be fine just using the "smart" req.body() helper instead:

API.add('POST', '/webhook', async function (req, res) {
    const body = await req.body()
    console.log(body) //=> will be text string
})

Appreciate it!

This is specifically for a Stripe Webhook, which signs the content as json, but will reject requests if you pull n a req.body() and pipe it through as JSON.stringify() (but will accept the raw request.text())

{
  cType: 'application/json; charset=utf-8',
  body: //{ big json object }
}

Just in case you missed it, 0.2.0 went out yesterday w/ this fix :)
