Allow to send session sessions when using a client manually

[rodolfoBee]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Reproduction Example/SDK Setup

import {
  BrowserClient,
  defaultStackParser,
  getDefaultIntegrations,
  browserSessionIntegration,
  makeFetchTransport,
  Scope,
} from "@sentry/browser";

// filter integrations that use the global variable
const integrations = getDefaultIntegrations({}).filter(
  (defaultIntegration) => {
    return !["BrowserApiErrors", "Breadcrumbs", "GlobalHandlers"].includes(
      defaultIntegration.name,
    );
  },
);

const client = new BrowserClient({
  dsn: "...",
  transport: makeFetchTransport,
  stackParser: defaultStackParser,
  integrations: [ ...integrations, browserSessionIntegration()],
  release:"directClient@1.0.0",
  autoSessionTracking:true,
  initialScope: {
    user: { id: 42, email: "john.doe@example.com" },
  },
});

const scope = new Scope();
scope.setClient(client);

client.init(); // initializing has to be done after setting the client on the scope
// rest of the logic

Steps to Reproduce

1. Run a simple app with the configuration above

Expected Result

The SDK sends release health sessions to Sentry to track release health and adoption on the Releases page.

Actual Result

No release session event is sent to Sentry.

Explicitly setting the browserSessionIntegration integration and/or autoSessionTracking have no effect on the result, this should also be automatic when a release version is set in the init as per:

• https://docs.sentry.io/platforms/javascript/configuration/releases/#release-health

Hello,
I'm gonna try to reproduce this. But one follow-up questions: How does the application look like where Sentry is running? Is this a browser extension or any other shared environment as a BrowserClient is explicitly created?

[ionutholbia]

@s1gr1d In our case Sentry is initialized in the service worker of a browser extension. I think @rodolfoBee also reproduced the issue but now sure how he tested.

in the service worker of a browser extension

The BrowserSession integration might not be set up correctly. Can you enable debug: true and check if you get a warning like this: "Using the browserSessionIntegration in non-browser environments is not supported.".

The SDK checks if WINDOW.document is available. I just want to check if you're running into this condition.

[ionutholbia]

The first print is mine.

Haven't received a print like: "Using the browserSessionIntegration in non-browser environments is not supported."

Maybe it's worth mentioning that if I initialize Sentry on a global scope using Sentry.init then Release healthy sessions work fine.
