SDK Setup

// apps/project/app/modules/sentry/monitoring.server.ts
import { nodeProfilingIntegration } from "@sentry/profiling-node";
import * as Sentry from "@sentry/remix";

export function init() {
 Sentry.init({
 dsn: import.meta.env.VITE_SENTRY_DSN,
 environment: import.meta.env.VITE_ENVIRONMENT,
 debug: true,
 autoInstrumentRemix: true,

 // Set tracesSampleRate to 1.0 to capture 100%
 // of transactions for performance monitoring.
 // We recommend adjusting this value in production
 tracesSampleRate: 1.0,
 profilesSampleRate: 1.0, // Profiling sample rate is relative to tracesSampleRate

 denyUrls: [
 /\/healthcheck/,
 // TODO: be smarter about the public assets...
 /\/build\//,
 /\/favicons\//,
 /\/images\//,
 /\/fonts\//,
 /\/apple-touch-.*/,
 /\/robots.txt/,
 /\/favicon.ico/,
 /\/site\.webmanifest/,
 ],

 integrations: [
 // Temporary disabling this because of https://github.com/getsentry/sentry-javascript/issues/12568
 // nodeProfilingIntegration(),
 // Add profiling integration to list of integrations
 Sentry.nativeNodeFetchIntegration(),
 Sentry.httpIntegration(),
 Sentry.httpClientIntegration(),
 ],

 beforeSendTransaction(event) {
 // ignore all healthcheck related transactions
 if (event.request?.headers?.["X-Healthcheck"] === "true") return null;

 return event;
 },
 });
}

// apps/project/app/entry.server.tsx

if (import.meta.env.VITE_SENTRY_DSN) {
 await import("./modules/sentry/monitoring.server.ts");
}

Steps to Reproduce

1. Launch remix app with remix vite:build
2. Open app in browser
3. An Internal server error occurs

__vite_ssr_import_0__.nativeNodeFetchIntegration is not a function
 at eval (/Users/simon/Code/Project/monorepo/apps/project/app/modules/sentry/monitoring.server.ts:32:27)
 at async instantiateModule (file:///Users/simon/Code/Project/monorepo/node_modules/.pnpm/vite@5.2.11_@types+node@20.12.12/node_modules/vite/dist/node/chunks/dep-cNe07EU9.js:55058:9

Expected Result

Integrations being added.

Actual Result

Integrations are not recognized and break the app.

@onurtemizkan could you take a look?

Hi @depsimon, are you using a built-in Remix server or an Express custom server in your project?

[depsimon]

@onurtemizkan It's the built-in Remix server locally. Deployed on Vercel if that matters, but the issue is happening locally as well.

[onurtemizkan]

So I guess the problem is that with the new version, the Sentry SDK should be initialized before any other imports to your server.entry. (This only applies for built-in Remix servers)

Even moving it to the top of the file before any other imports won't help because ESBuild reorders the imports (which is out of our control) in the bundle. So the workaround for that for the time being is running the remix server with --require or --import like:

NODE_OPTIONS='--import=./instrument.server.mjs' remix-serve build
# or
NODE_OPTIONS='--require=./instrument.server.cjs' remix-serve build

If that doesn't help, you can also try removing autoInstrumentRemix from your init config to fall back to the non-OTEL implementation to check if it resolves the issue.

The docs are updated so you can refer to: https://docs.sentry.io/platforms/javascript/guides/remix/manual-setup/
