Description

I'm trying to use Sentry's javascript SDK with cloudflare workers, however I'm getting an error using either @sentry/minimal, @sentry/browser or raven-js.

The code is at available at https://github.com/tutorcruncher/cloudflare-worker and a preview is avilable at https://cloudflareworkers.com/#8dc47c7e9bd4a5463e6495630f82b7e9:https://workers.tutorcruncher.com although I'm not sure how long that will last for.

If the preview has stopped working you should be able to run a new preview with simply yarn && python preview.py.

Uncaught TypeError: dist.init is not a function
    at Module.<anonymous> (worker.js:1863:13)
    at __webpack_require__ (worker.js:20:30)
    at worker.js:84:18
    at worker.js:87:10

I also tried @sentry/browser but an error The 'referrerPolicy' field on 'RequestInitializerDict' is not implemented. which makes sense. raven-js gave yet another error.

I'm aware of https://blog.cloudflare.com/dogfooding-edge-workers/ but I was hoping to use the standard sentry sdk.

[samuelcolvin]

I've updated the code to log errors to sentry directly and that's working fine.

If you want to replicate the error you'll need to use this commit which actually uses raven-js and edit from there, I don't have a commit with @sentry/minimal or @sentry/browser I'm afraid.

How does your import / require statement look like of @sentry/browser?

[samuelcolvin]

I think you mean @sentry/minimal? (@sentry/browser failed with an understandable error about referrerPolicy)

Here's my code:

import * as Sentry from '@sentry/minimal'
import {Request, router} from './src/utils'
import test from './src/test'

Sentry.init({dsn: process.env.RAVEN_DSN})

const routes = {
  default: test
}

async function handle_request(raw_request) {
  const request = new Request(raw_request)
  await request.prepare()
  Sentry.captureMessage(`request ${request.url}`, {extra: {request: request.debug_info()}})
  try {
    const handler = router(routes)
    return handler(event.request)
  } catch (e) {
    Sentry.captureException(e)
  }
}

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

And here's a branch with that code on it.

And here's a worker preview with that code running.

Just to confirm, personally I don't need this anymore as I spent Friday afternoon ignoring my real work and building my own sentry logger which plays nicely with web worker's event.waitUntil() and even uploads source maps to sentry so I get full traces.

[samuelcolvin]

(and let's me include extra in captureMessage #1666 😉)

[HazAT]

You can write your own transport class and still use Sentry.

[samuelcolvin]

would that solve the dist.init is not a function problem?

[HazAT]

No, but I referrerPolicy error, I think.
tbh I am not sure where this is coming from though.

The initially reported issue is resolved I guess, so let me close it. Feel free to ping me if this still needs to be reopened. Cheers!
