Reproduction Example/SDK Setup

Hey,
which integrations should I expect to work in bun? So far only manual instrumentation seems to be working.
Is this expected behavior? If so, a few more notes on that would be appreciated in the documentation.

Bun

import * as Sentry from "@sentry/bun";

// Ensure to call this before importing any other modules!
Sentry.init({
	dsn: DSN,
	debug: true,
	// Add Performance Monitoring by setting tracesSampleRate
	// Set tracesSampleRate to 1.0 to capture 100% of transactions
	// We recommend adjusting this value in production
	tracesSampleRate: 1.0,
});

import "./instrument.ts";
import * as Sentry from "@sentry/bun";

await Sentry.startSpan(
	{
		op: "test",
		name: "My First Test Transaction in bun",
	},
	async () => {
		await fetch(`https://google.com`);
	},
);

const sleep = () => new Promise((res) => setTimeout(() => res("hi"), 3000));

await sleep();
throw new Error("I just crashed Bun");
`

Node
`
import * as Sentry from "@sentry/node";

// Ensure to call this before importing any other modules!
Sentry.init({
	dsn: DSN,
	debug: true,
	// Add Performance Monitoring by setting tracesSampleRate
	// Set tracesSampleRate to 1.0 to capture 100% of transactions
	// We recommend adjusting this value in production
	tracesSampleRate: 1.0,
});

Steps to Reproduce

Expected Result

Expected http instrumentation to work, according to docs (See result for node below)

https://docs.sentry.io/platforms/javascript/guides/bun/configuration/integrations/http/

Actual Result

error handling is noted as not working in the npm package page, so i guess that is to be expected

@AbhiPrasad should fetch client instrumentation work for bun work?

Hi @doepnern, thanks for filing this. Unfortunately this is still an issue upstream in bun, see oven-sh/bun#13165.

You should filter out the http integration for the time being.

import * as Sentry from '@sentry/bun';

Sentry.init({
  dsn: '__MY_DSN__',
  integrations: function (integrations) {
    // integrations will be all default integrations
    return integrations.filter(function (integration) {
      return integration.name !== "Http";
    });
  },
  tracesSampleRate: 1.0,
});

From what I can tell, I'm supposed to get automatic instrumentation with PostgreSQL, Redis, and more. Yet I am not seeing the data for this stuff being received.

@MatthewAry are you running your app with CJS or ESM? ESM might be causing issues here for instrumentation.
