Getting Origin header

[EduM22]

Is there any way to get the origin header/request object in the .catch error handler?
I want to send the CORS headers back with the correct headers.

Sorry I'm just now seeing this! Wish GH would add badges next to Discussions for unanswered ones...

Perhaps try something like this?

// index.js
import { Router } from 'itty-router'
import { error } from 'itty-router-extras'

const router = Router()

// add routes (not shown)

export default {
  fetch: (request, ...args) => router
                        .handle(request, ...args)
                        .catch((err) => {
                          const referer = request.headers.get('Referer')
                          // do something with it
                          
                          return error(500, 'Not really a 500, but you get the point')
                        })
}
