Sentry.init({

      try {
        const { query, variables } = JSON.parse(hint.input);
        if (!breadcrumb.data) breadcrumb.data = {};
        breadcrumb.data.query = query;
        breadcrumb.data.variables = variables;
      } catch {}

    return breadcrumb;

  // Don't auto initialize, instead we do it manually

});

Note that we've just now disabled auto initialization, the issue at hand was present before we did disabled this.

I have following issue:

Every new release suddenly started having empty Android bundles, giving us the Invalid location in sourcemap errors at the top of Android-reported events.
Using the Sentry CLI to debug the particular events reveals the same and the sourcemap uploads in the project Settings also clearly shows it's empty (see screenshot).

Note that this used to work in the past, but it's hard to debug where it started occurring since the older events are long removed due to retention periods.

For iOS, this works perfectly and all is well.

Steps to reproduce:
Just make a release bundle, which automatically uploads the bundle to our Sentry environment.

Actual result:

Minified stack traces in our events and an error banner on top.

Expected result:

Proper reported events with stack traces

@StampixSMO RN 0.70.6 has Hermes enabled by default, not sure if you had before.
https://docs.sentry.io/platforms/react-native/manual-setup/hermes/
Also, take a look at this https://docs.sentry.io/platforms/react-native/troubleshooting/#react-native-069-and-higher
Besides upgrading the SDK to the latest version, let us know if that helps.

[StampixSMO]

Hi @marandaneto Thanks for the reply, appreciated!

We've had Hermes quite a while already, so don't think that's the issue here. Additionally, we've got the latest SDK version (see above) in the issue description.
The issue is also that the bundle is 0MB, the source maps seem to be fine and are uploaded correctly as far as I can tell, see the screenshot above.

For the react-native.config.js adjustments, we have this patch file so that should all be good already

Any further suggestions we can try?

Edit: also adding the output of our build:

[marandaneto]

@StampixSMO being 0 bytes is fine I don't remember if for Hermes or RAM bundles, have to check it.
@krystofwoldrich will further investigate.

[krystofwoldrich]

Hi @StampixSMO,
could you send us an example app with instructions on how to build it so we can reproduce the issue?

[StampixSMO]

Hi @StampixSMO, could you send us an example app with instructions on how to build it so we can reproduce the issue?

Publicly I cannot easily share an example app without reproducing our entire app including fastlane CI etc .. Is there an option to privately share this?

Using bare workflow btw

[krystofwoldrich]

@StampixSMO Would you be able to recreate the issue with a clean project, just setting up the minimum needed, maybe the issue show even without Fastlane?

[marandaneto]

A minimal reprocible exampe would do, that means.

npx react-native init Name
yarn add @sentry/react-native
npx @sentry/wizard -i reactNative -p ios android

Steps to reproduce...
