I have following issue:

I followed this guide to upload source maps to sentry. The source maps work when the error is sent from the app in dev mode, but when the error is received from the app built for release, the source maps are not working.

Hi,
thank you for the message and the links,
are the source maps not working for both Android and iOS release builds?

How do you enable source maps in your iOS builds, using EXTRA_PACKAGER_ARGS or SOURCEMAP_FILE?

Hermes source maps guide

I see that you uploaded both Release Bundles and Artifact Bundles, Artifact Bundles are our new way of handling source maps I would recommend keeping that and deleting the Release Bundles. Likely you upgrade sentry-cli while working on the source maps.

Hi,
Yes, source maps are not working for both platforms, for Android in dev env. working , but here the released version and they do not.

Looking at the document again, I somehow skipped/forgot about this :( .

Hi,
From the last time, I updated the @sentry/react-native to version 5.5.0 and @sentry/cli to version 2.18.1.

Now, when I send the error from a simulator, the sourcemaps are working, but I see this error in sentry.

Integrate Sentry into your release pipeline using a tool like Webpack or the CLI. Your release must match what's set in your Sentry.init. The value for this event is ...

I am unsure why I get this error because I checked it, and the release variable sent with each event has the same value as release I used to upload source maps. Or am I missing something?

Hi,
the issue is from dev environment. That's symbolicated on the simulator. To verify if the source maps are working can you try to build a release version of your app and send the error?

Hi,
tried it with release version, and it's working 🎉 , but I also this second error not sure if it should work. I will try android

Awesome to hear, the second error is issue tracked here. So I will close this now. In case of any other issues, we can reopen this one or create a new one.
