Use profiling-node in Astro project

[JuJup]

Did anybody already got profiling-node working in an Astro project (using SSR)?
Following the docs, it should be possible somehow..
I first tried the following:

import sentry from "@sentry/astro";
import * as Sentry from "@sentry/browser";
import { nodeProfilingIntegration } from "@sentry/profiling-node";

export default defineConfig({
  integrations: [
    sentry({
      dsn: <dsn>,
      sourceMapsUploadOptions: {
        project: "astro",
        authToken: <auth-token>,
      },
      integrations: [
        Sentry.browserProfilingIntegration(),
        nodeProfilingIntegration(),
      ],
      tracesSampleRate: 0.25,
      profilesSampleRate: 0.5
    }),
    ]
  ],

This gives me error traces, but unfortunately no profiling.
Then I tried adding an explicit sentry.server.config.js as mentioned for manual setup in the docs with the following content:

import * as Sentry from "@sentry/astro";
import { nodeProfilingIntegration } from "@sentry/profiling-node";

Sentry.init({
    dsn: <dsn>,
    integrations: [
      nodeProfilingIntegration(),
    ],
    tracesSampleRate: 1.0,
    profilesSampleRate: 1.0,
});

Still no success :(
Anybody got some tips to help me getting this nice feature running?
