@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?

I have the exact same issue except with Cloudflare Workers, traces are working fine, but my thrown errors aren't appearing in issues. Set it up just now using the Configure Cloudflare Workers SDK docs on a new Cloudflare Workers project.

Note: Calling Sentry.captureException works as expected.
