Release info is not sent in the event payload (7.24.0 breaks it)

[pawojciechowski]

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?

Sentry Saas (sentry.io)

Which package are you using?

@sentry/nextjs

SDK Version

7.25.0

Framework Version

Next.js 12.1.5, React 17.0.2

Link to Sentry event

No response

Steps to Reproduce

I've noticed that release info in events stopped being sent after upgrading Sentry 7.14.2 -> 7.24.2. I've tried to upgrade to 7.25.0, but the behavior is the same. I debugged it, and it seems like 7.24.0 breaks this feature (release info is sent correctly with previous versions).

Expected Result

Release info is sent along with the events & it is visible in Sentry UI.

Actual Result

Release info is not sent in the event payload despite it being correct & available on the window.SENTRY_RELEASE.
Releases are correctly sent while building the app & visible in the Sentry UI (https://sentry.io/organizations/<org_id>/releases/)

Hi @pawojciechowski, thanks for writing in!

Have you tried reproducing this in version 7.23.0? I'm asking because in this version, we added the (yet unused) __SENTRY_RELEASE__ magic string variable in #6322. Are you by chance using this variable to set releases?

Otherwise, we might need to look at #6404 which changed release injection for NextJS (cc @lforst)

[pawojciechowski]

I've tried 7.23.0, and it worked there. I rely on auto release injection provided by withSentryConfig. I don't use anything custom around there.

I think I might know what's going on. I think with #6404 we accidentally removed the "release suggestion" mechanism Sentry CLI provides because we're only reading the Webpack plugin options or environment variables to determine the release value. We gotta fix this.
