Sentry.init()

See full file here https://github.com/bluesky-social/social-app/blob/main/src/logger/sentry/setup/index.ts

import {init} from '@sentry/react-native'

import * as env from '#/env'

init({
  enabled: !env.IS_DEV && !!env.SENTRY_DSN,
  dsn: env.SENTRY_DSN,
  environment: env.ENV, // production | development | testflight
  dist: env.BUNDLE_IDENTIFIER,
  release: env.RELEASE_VERSION,
  ignoreErrors: [...],
  sampleRate: env.IS_INTERNAL ? 1.0 : 0.1,
})

Steps to Reproduce

See our GitHub Action build step here https://github.com/bluesky-social/social-app/blob/main/.github/workflows/build-submit-ios.yml#L93-L101

- name: 🏗️ EAS Build
  run: >
    SENTRY_AUTH_TOKEN=${{ secrets.SENTRY_AUTH_TOKEN }}
    SENTRY_RELEASE=${{ steps.env.outputs.EXPO_PUBLIC_RELEASE_VERSION }}
    SENTRY_DIST=${{ steps.env.outputs.EXPO_PUBLIC_BUNDLE_IDENTIFIER }}
    yarn use-build-number-with-bump
    eas build -p ios
    --profile ${{ inputs.profile || 'testflight' }}
    --local --output build.ipa --non-interactive

During eas build, the xcode Build Phase that this library injects uploads debug files to Sentry.

Expected Result

We expect a Mach-O debug companion file to be uploaded for the Bluesky package.

Actual Result

We get a Mach-O executable for Bluesky, but no debug file. Other packages have both an executable and a debug file. See below for an example of a recent build.

I've been investigating this issue for the past day and have identified a solution that seems to work for us. I've implemented that and outlined the full details in bluesky-social/social-app#9242, which I'll reproduce below.

Sentry definitely does its own work internally to get all the debug files. This happens during the Upload Debug Symbols to Sentry, which is added by the Sentry Expo plugin to XCode's Build Phases. But it does not appear to find the .dSYM files for the main Bluesky bundle on its own.

To output the .dSYM files, our eas build command has been updated from --output build.ipa (which outputs just the app bundle) to --output build.tar.gz. This produces a gzipped tarball that includes the .ipa and other artifacts.

This tarball alone does not include the .dSYM files. To include those, we need to add buildArtifactPaths to the eas.json config. NOW after running eas build, the tarball contains a Bluesky.app.dSYM.zip file.

Manual upload

So now our build outputs a tarball, which we uncompress. We can then eas submit the included .ipa, and separately upload the .dSYM.zip to Sentry manually.

I'm sure we're missing something, but I'm not sure where to look. As noted in the PR, we were missing some required config (some additions to our Apple Privacy Manifest), but I believe we otherwise have Sentry configured in a standard fashion.

The manual upload seems to work fine for us for now, but I would love to have confirmation that this is a viable approach, or any ideas on what's missing that would allow Sentry to do this automatically.

If there's any other help or debugging I can provide, please let me know.

[estrattonbailey]

Working on some debug logs with SENTRY_LOG_LEVEL=debug, will post those when I have them.

Welp, guess they were swallowed at some point, so that wasn't much help. The full build is here: https://github.com/bluesky-social/social-app/actions/runs/18698396243/job/53321549688

Thank you for the detailed report @estrattonbailey 🙇
We will investigate this and iterate back.

is manual upload to sentry the only option right now?
