#Astro - Enable Profiling

I'm attempting to enable profiling in an Astro project. The SDK is correctly configured to send errors. The integration is configured with

sentry({
  dsn: "...",
  environment: 'production',
  tracesSampleRate: 1,
  replaysSessionSampleRate: 1,
  replaysOnErrorSampleRate: 1,
  sourceMapsUploadOptions: {
    project: "...",
    authToken: process.env.SENTRY_AUTH_TOKEN,
  },
  enabled: true,
}),

The sentry.server.config.js file looks like

Sentry.init({
  dsn: '...',
  environment: "production",
  integrations: [nodeProfilingIntegration()],

  tracesSampleRate: 1,
  profilesSampleRate: 1,
  profileSessionSampleRate: 1,
  profileLifecycle: "trace",
  enabled: true,
})

The file is at least being loaded, but nothing shows in profiling in the dashboard.

Running Node 22.14, latest version of the Astro SDK & profiling package, on MacOS.

I only found one discussion https://github.com/getsentry/sentry-javascript/discussions/13514 about setting this up with no response

Tried posting this in the SDK channel recommended at the top of this channel, but it failed to post there

these options are for two different profiling modes:

  profilesSampleRate: 1,
  profileSessionSampleRate: 1,
  profileLifecycle: "trace",

can you try either:

  profilesSampleRate: 1,

  profileSessionSampleRate: 1,
  profileLifecycle: "trace",

and adding debug:true to see the SDK logs in the app console, this will help you understand why profiles are not sent

truncated, this is what I see with profilesSampleRate. looks to be the same with the other options

do you see Sentry Logger [log]: Integration installed: ProfilingIntegration when the app starts?

i was trying to reproduce the issue on my side, but not being an astro developer I failed to create a task that generates enough samples for a profile to be build and sent.
the line with the integration initialising should make the SDK send profiles, or at least log lines starting with [profiling]
