Unable to instrument Nestjs app when the Fastify Adapter is used

[samuelgoldenbaum]

Is there an existing issue for this?

• [x] I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• [x] I have reviewed the documentation https://docs.sentry.io/
• [x] 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/nestjs

SDK Version

8.26.0

Framework Version

@nestjs/platform-fastify ^10.4.1

Link to Sentry event

No response

Reproduction Example/SDK Setup

The following will not instrument...

const initSentry = (): Promise<void> => {
  return new Promise((resolve) => {
    Sentry.init({
      dsn: 'DSN,
      integrations: [nodeProfilingIntegration()],
      tracesSampleRate: 1.0,
      profilesSampleRate: 1.0
    });
    return resolve();
  });
};

async function bootstrap() {
  const app = await NestFactory.create<NestFastifyApplication>(
    AppModule,
    new FastifyAdapter()
  );

  await app.listen(3000);
}

initSentry().then(() => bootstrap());

But using Express will

const initSentry = (): Promise<void> => {
  return new Promise((resolve) => {
    Sentry.init({
      dsn: 'DSN',
      integrations: [nodeProfilingIntegration()],
      tracesSampleRate: 1.0,
      profilesSampleRate: 1.0
    });
    return resolve();
  });
};

async function bootstrap() {
  const app = await NestFactory.create(AppModule);

  await app.listen(3000);
}

initSentry().then(() => bootstrap());

Steps to Reproduce

Swap to the Fastify adapter:

  const app = await NestFactory.create<NestFastifyApplication>(
    AppModule,
    new FastifyAdapter()
  );

  await app.listen(3000);

Expected Result

Should instrument and show data in Performance tab

Actual Result

No instrumentation

@samuelgoldenbaum thanks for writing in.

Could you add debug: true to your Sentry.init and share the sentry logs for the fastify setup?

Implementation:

import 'dotenv/config'; // needed as we init Sentry before bootstrapping Nest
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

import * as Sentry from '@sentry/nestjs';
import { nodeProfilingIntegration } from '@sentry/profiling-node';
import {
  FastifyAdapter,
  NestFastifyApplication
} from '@nestjs/platform-fastify';

const initSentry = (): Promise<void> => {
  return new Promise((resolve) => {
    Sentry.init({
      dsn: process.env.SENTRY_DSN,
      integrations: [nodeProfilingIntegration()],
      tracesSampleRate: 1.0,
      profilesSampleRate: 1.0,
      debug: true
    });
    return resolve();
  });
};

async function bootstrap() {
  const app = await NestFactory.create<NestFastifyApplication>(
    AppModule,
    new FastifyAdapter()
  );

  await app.listen(3000);
}

initSentry().then(() => bootstrap());

Hey @samuelgoldenbaum thanks for writing in!

We'll look into your issue next week as this week is Hackweek at Sentry (see #13421).

[lforst]

@samuelgoldenbaum can you try set up the SDK like it is recommended here: https://docs.sentry.io/platforms/javascript/guides/fastify/#configure

It might be the case that Sentry.init() is running too late and isn't able to patch the fastify imports. Thanks!

[ctjhoa]

Looks like I manage to make it work like this

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

  async function bootstrap() {
    const fastifyAdapter = new FastifyAdapter();
    Sentry.setupFastifyErrorHandler(fastifyAdapter.getInstance());
    const app = await NestFactory.create<NestFastifyApplication>(AppModule, fastifyAdapter);
  }
