Errors reported to Sentry, but stack trace is all "Unknown"

Environment

How do you use Sentry? Sentry SaaS (sentry.io)

Which SDK and version? sentry.javascript.react-native v. 2.4.2

Steps to Reproduce

I have no idea.

• React-Native app, ejected from Expo SDK 41
• I am running expo publish --release-channel release to create a release

Expected Result

I would look at the log entry and happily continue debugging.

Actual Result

Here’s what I’m seeing in the Sentry dashboard:

This makes sense since here’s what the stack trace looks like:

Error: Text strings must be rendered within a <Text> component.

The release artefacts are being sent correctly:

So I looked at the raw data, and it appears that the bundles are not referenced and instead called de6b708ef4031fd66a9ac4afafdfa031.

My Sentry code looks like this:

Sentry.init({
  dsn: config.sentryDSN,
  enableInExpoDevelopment: true,
  debug: __DEV__,
});

Any ideas why this is?

I finally got it to assign the correct release to events from OTA bundles by overriding both dist and release which means the default settings are not working. Is this because I’m importing from @sentry/react-native instead of sentry-expo since I’m using the bare workflow? I’ve tried using sentry-expo but then the app fails to start.

Regardless, the stack traces were still using Updates.manifest.bundleKey rather than ~/main.jsbundle like the artifacts uploaded by the postPublish hook.

I was able to finally get them working by also rewriting the frames as suggested in the “Self-hosting OTA?” section (even though I’m not hosting the bundles myself).

The final working version looks like this:

import * as Sentry from '@sentry/react-native';
import {RewriteFrames} from "@sentry/integrations";
import * as Updates from 'expo-updates';
import type {ReactNativeOptions} from "@sentry/react-native/dist/js/options";
import type {AppManifest} from "expo-constants/build/Constants.types";

const sentryOptions: ReactNativeOptions = {
    dsn: '...',
    new RewriteFrames({
        iteratee: frame => {
            if (frame.filename) {
                frame.filename = Platform.OS === 'android'
                    ? 'app:///index.android.bundle'
                    : 'app:///main.jsbundle'
            }
            return frame;
        }
    })
};

if (Updates.manifest) {
    const manifest = Updates.manifest as AppManifest;
    if (manifest.revisionId)
        sentryOptions.release = manifest.revisionId;
    if (manifest.version)
        sentryOptions.dist = manifest.version;
}

Sentry.init(sentryOptions);

Either the docs need updating to clarify this must be done manually (regardless of self hosting) or there’s something broken in the bare workflow’s default settings that needs fixing.

@marandaneto Closing as this is expo related only.
