Source Maps from production errors - React Native

I set up Sentry on RN, following these instructions:

The source map is perfect when I throw some error with the debug release, but when I try to generate a release in order to test the error source maps in production, that’s the result:

For some reason, instead of showing the JS code, it shows the native code.

The command that I’m running to generate the release:

yarn react-native ios --configuration Release

And the function responsible to initialize Sentry:

import * as Sentry from "@sentry/react-native";

    export const configureSentry = (): void => {
      if (__DEV__) {

        dsn: "",
