@sentry/cloudflare not reporting errors thrown from Durable Objects

[jczstudios]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/cloudflare

SDK Version

9.34.0

Framework Version

9.34.0

Link to Sentry event

No response

Reproduction Example/SDK Setup

import { DurableObject } from "cloudflare:workers";
import * as Sentry from "@sentry/cloudflare";

class MyDurableObjectBase extends DurableObject<Env> {
	constructor(ctx: DurableObjectState, env: Env) {
		super(ctx, env);
	}

	async sayHello(name: string): Promise<string> {
		throw new Error("Should be recorded in Sentry.")
	}
}

export const MyDurableObject = Sentry.instrumentDurableObjectWithSentry(
	(env: Env) => ({
	  dsn: "__YOUR_DSN__",
	  tracesSampleRate: 1.0,
	  debug: true
	}),
	MyDurableObjectBase,
);

export default {
	async fetch(request, env, ctx): Promise<Response> {
		const id: DurableObjectId = env.MY_DURABLE_OBJECT.idFromName("foo");

		const stub = env.MY_DURABLE_OBJECT.get(id);

		const greeting = await stub.sayHello("world");

		return new Response(greeting);
	},
} satisfies ExportedHandler<Env>;

Steps to Reproduce

1. Send fetch request to a worker instrumented with Sentry.instrumentDurableObjectWithSentry where the Durable Object RPC method throws when called by the worker. (see example above)
2. No Sentry logs (console) / errors are recorded.

Expected Result

Sentry should record errors thrown according to the docs

Additionally, since debug: true is set, there should be debug logs from the Sentry library.

Actual Result

No debug logs visible, no errors reported to Sentry.

Hi @jczstudios, thanks for filing this. We'll take a look.

I'm going to pass this off to @timfish given he's been touching cloudflare stuff recently and I don't have time to follow up - could you take a look?
