SDK Setup

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

import {
  BrowserClient,
  Breadcrumbs,
  Dedupe,
  defaultStackParser,
  getCurrentHub,
  GlobalHandlers,
  makeFetchTransport,
  LinkedErrors,
  HttpContext,
  FunctionToString,
  InboundFilters
} from '@sentry/browser';
const isProd = process.env.NODE_ENV === 'production';
const config = {
  dsn: typeof SENTRY_DSN !== 'undefined' ? SENTRY_DSN : '',
  environment: typeof ENV !== 'undefined' ? ENV : 'unknown',
  sampleRate: isProd ? 0.7 : 0,
  tracesSampleRate: 0
};
const client = new BrowserClient({
  // all options you normally pass to Sentry.init
  ...config,
  // ...

  transport: makeFetchTransport,
  stackParser: defaultStackParser,
  // Only the integrations listed here will be used
  integrations: [
    new Breadcrumbs(),
    new GlobalHandlers(),
    new LinkedErrors(),
    new Dedupe(),
    new HttpContext(),
    new InboundFilters(),
    new FunctionToString()
  ]
});

getCurrentHub().bindClient(client);

Sentry.setTag('platform', 'unknown');

Steps to Reproduce

1. The above SDK setup taken from https://docs.sentry.io/platforms/javascript/configuration/tree-shaking/
2. See user sessions are not being tracked.

Expected Result

User sessions should be tracked right

Actual Result

// This file configures the initialization of Sentry on the server.
// The config you add here will be used whenever the server handles a request.
// https://docs.sentry.io/platforms/javascript/guides/nextjs/

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

const isProd = process.env.NODE_ENV === 'production';

Sentry.init({
  dsn: process.env.SENTRY_DSN || '',
  authToken: process.env.SENTRY_AUTH_TOKEN,
  environment: process.env.ENV || 'unknown',
  sampleRate: isProd ? 0.7 : 0,
  tracesSampleRate: 0
});

This works and tracks the user session

[bhuvanesh-hotstar]

Sentry config given here https://docs.sentry.io/platforms/javascript/configuration/tree-shaking , does not track user sessions somehow and the crash reporting dashboard shows incorrect values as user sessions are ideally 0, errors are being tracked correctly though

[lforst]

Oh yeah, when creating a custom client you currently have to manually start sessions as they are normally created and in the Sentry.init().

We should probably make this part of the individual clients instead.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you remove the label Waiting for: Community, I will leave it alone ... forever!
