Unhandled promise rejections are not logged to sentry

My feature request is connected to the bug https://github.com/getsentry/sentry-react-native/issues/1077.

I’ve tried the solution from docs, but it didn’t work out for me. So I found another solution with polyfilling existing Promise in React Native.

I’ve used this package

import { setUnhandledPromiseRejectionTracker } from 'react-native-promise-rejection-utils';
import { getCurrentHub } from '@sentry/core';
setUnhandledPromiseRejectionTracker((id, error) => {
  getCurrentHub().captureException(error, {
    data: { id },
    originalException: error,
  });
});

Inside the react-native-promise-rejection-utils package polyfills the existing promise. You can check it out here

So I propose changing the method, removing the check for the promise version and using the package react-native-promise-rejection-utils or polyfill directly without relaying on this package.

I think this solution is better in many ways:

1. It doesn’t require user to do or check anything. It just works
2. _checkPromiseVersion can be removed

I have the same issue. I did match the versions, but that doesn’t help.

grep "promise" node_modules/react-native/package.json
    "promise": "^8.0.3",
grep "promise" ./package.json
    "promise": "^8.0.3"

Possible Unhandled Promise Rejection (id: 0):
TypeError: Attempted to assign to readonly property.

Also, setting debug: true doesn’t show me the [Sentry] Unhandled promise rejections will be caught by Sentry. message.

I have the same issue with:

• RN 0.66.4
• Android
• iOS
• Hermes: yes
• “@sentry/react-native”: “^3.2.10”,

Please issue an urgent fix. Thanks!
