No signs of Fastify tracing

[punkpeye]

I am using Fastify to serve a react-router app.

I start my server following the ESM instructions:

dotenvx run -f .env.production -- node --import ./app/bin/instrument.ts ./app/bin/start-server.ts

my Sentry options look as follows:

const sentryOptions = {
  dsn: config.SENTRY_DSN,
  environment: config.ENVIRONMENT,
  integrations: [
    Sentry.extraErrorDataIntegration({
      captureErrorCause: true,
      depth: 7,
    })
  ],
  maxValueLength: 1_024 * 10,
  normalizeDepth: 7,
  profilesSampleRate: 1,
  registerEsmLoaderHooks: true,
  release: config.RELEASE_VERSION,
  sendDefaultPii: true,
  skipOpenTelemetrySetup: false,
  tracePropagationTargets: [
    'localhost',
    '127.0.0.1',
    /^https:\/\/glama\.ai\//u,
  ],
  tracesSampler: (samplingContext) => {
    return true;
  },
} satisfies NodeOptions;

here is what I see after the server starts:

Sentry Logger [debug]: @opentelemetry/instrumentation-fastify Applying instrumentation patch for module on require hook {
  module: 'fastify',
  version: '5.3.2',
  baseDir: '/Users/frank/Developer/punkpeye/glama/node_modules/.pnpm/[email protected]/node_modules/fastify'
}
[Sentry] fastify is not instrumented. Please make sure to initialize Sentry in a separate file that you `--import` when running node, see: https://docs.sentry.io/platforms/javascript/guides/fastify/install/esm/.

but after that... nothing related to Fastify.

I get pg traces, but not Fastify.

In general, my traces look pretty bare bones.

What am I missing?

Copying @andreiborza @mydea @onurtemizkan

Been stuck on this for weeks. Would greatly appreciate help figuring out what's missing.

Hi @punkpeye, the current version of the SDK uses @opentelemetry/instrumentation-fastify, which doesn't support fastify versions 5.x.x. We'll soon release #15542, and with that, we'll be supporting Fastify 5.

[punkpeye]

oh god. so much time wasted 😢

This should have been a big red warning on https://docs.sentry.io/platforms/javascript/guides/fastify/opentelemetry/

@onurtemizkan is there some way to install a preview/prerelease version of the SDK that has #15542 included in it? I am struggling to get my server instrumented and don't mind using a release that is not officially out yet.

@erikmunson you could checkout the branch and run yarn && yarn build && yarn build:tarball to build all packages as tarballs, then pick the one you want and add it to your project. But obviously it might not be in a release ready state.
