Sentry React Native Issue: Unhandled Promise Rejections

Overview

This repository demonstrates an issue encountered with Sentry in a React Native application, specifically regarding the handling of unhandled promise rejections. Sentry for React Native promises out-of-the-box functionality to capture unhandled promise rejections, but it appears not to be functioning as expected.

Sentry's declaration in regards to unhandled promises

Github issue #1

Github issue #2

Issue Description

When unhandled promise rejections occur in the React Native application, Sentry does not seem to capture these errors consistently or at all. This behavior is contrary to Sentry's documentation and expectations for React Native applications.

Environment

• React Native Version: [Specify version]
• Sentry Version: [Specify version]

Reproduction of the Issue

This repository contains a minimal React Native setup where this issue can be reproduced.

Steps to Reproduce

1. Clone this repository.
2. Install dependencies using npm install or yarn.
3. Run the application on a simulator or physical device.
4. Trigger an unhandled promise rejection using [describe the method or action].
5. Observe the behavior in the Sentry dashboard.

Expected Behavior

Sentry should capture and report all unhandled promise rejections, as per its documentation for React Native integration.

Actual Behavior

Unhandled promise rejections are not captured or reported in some or all cases.

Note: This repository and README are intended for collaborative troubleshooting and finding a resolution to the Sentry React Native issue regarding unhandled promise rejections.

This is a new React Native project, bootstrapped using @react-native-community/cli.

Getting Started

Note: Make sure you have completed the React Native - Environment Setup instructions till "Creating a new application" step, before proceeding.

Step 1: Start the Metro Server

First, you will need to start Metro, the JavaScript bundler that ships with React Native.

To start Metro, run the following command from the root of your React Native project:

# using npm
npm start

# OR using Yarn
yarn start

Step 2: Start your Application

Let Metro Bundler run in its own terminal. Open a new terminal from the root of your React Native project. Run the following command to start your Android or iOS app:

For Android

# using npm
npm run android

# OR using Yarn
yarn android

For iOS

# using npm
npm run ios

# OR using Yarn
yarn ios

If everything is set up correctly, you should see your new app running in your Android Emulator or iOS Simulator shortly provided you have set up your emulator/simulator correctly.

This is one way to run your app — you can also run it directly from within Android Studio and Xcode respectively.

Step 3: Modifying your App

Now that you have successfully run the app, let's modify it.

1. Open App.tsx in your text editor of choice and edit some lines.

2. For Android: Press the R key twice or select "Reload" from the Developer Menu (Ctrl + M (on Window and Linux) or Cmd ⌘ + M (on macOS)) to see your changes!

   For iOS: Hit Cmd ⌘ + R in your iOS Simulator to reload the app and see your changes!

Congratulations! 🎉

You've successfully run and modified your React Native App. 🥳
