com.microsoft.codepush.react.CodePushMalformedDataException Unable to parse contents of [..]/codepush.json

[maxkomarychev]

Hi,

this is the crash report I've got from crash-analytics service. I wasn't able to reproduce it myself however whatever happens the codepush should not crash, it should safely fallback to original bundle if error happened during it's initialization.

Expected Behavior

CodePush should not crash the app. It should safely fallback to original bundle.

Actual Behavior

App crashes.

Reproducible Demo

• If you can't reproduce the bug on it, provide us as much info as possible about your project

I do have this
apply from: "../../node_modules/react-native-code-push/android/codepush.gradle" line in build.gradle

Environment

• react-native-code-push version: 5.2.1
• react-native version: 0.50.3
• iOS/Android/Windows version: android 7.0
• Does this reproduce on a debug build or release build?
• Does this reproduce on a simulator, or only on a physical device?
  Happened dozen of times on release build on physical device.

Hi @maxkomarychev, thanks for reaching us.

CodePush should not crash the app. It should safely fallback to original bundle.

Absolutely agreed, to have good UX we definitely should not crash an app while installing broken CodePush update. Currently, we are actively working on CodePush native SDKs (both Android and Apple) migration to the App Center native SDKs, while migrating we are going to fix such kind of problems in addition to general rollbacks enhancement (add an ability to see the reason of rollbacks). The migration process will take some time and when we have it finished - you'll be able to use appcenter-codepush service from the https://github.com/Microsoft/AppCenter-SDK-React-Native/ with all the improvements I've listed above.

Please also let me know if you see any other issues or have any questions.

[maxkomarychev]

thanks! do you have any ETA/roadmap on when those new SDKs will be available?

We have this issue reported in our app too both in Sentry and Crashlytics, and likewise haven't been able to reproduce it ourselves.

Our current 7-day metrics for this crash indicate that out of our about 2k weekly active users, 40 users see this crash every week (they're not the same week after week BTW), so roughly 2% of our userbase is affected. It is not a major issue for us, but it is also not rare enough that it doesn't produce some discomfort.

We don't know what the root cause is, but are considering working on a fix to at least prevent CodePush from crashing the app when this happens.

Seeing this on a production app as well. As suggested before, CodePush should probably fallback to the original bundle rather than crashing.

[jchirik]

Im getting this as well. please fix!

Also happening here, however it seems to only occur in a specific device (Twist S520).
