Work Around (TLDR)

Add the polyfill to your dependencies.

npm install --save promise.allsettled

Then add the following to somewhere near the root of your app (such as index.js).

import allSettled from 'promise.allsettled';

allSettled.shim();

---

Explanation

The issue is that the polyfill for Promise used by Hermes does not include Promise.allSettled (or Promise.any). react-native@0.70.6 added support for Promise.allSettled (and Promise.any). However, React Native will use the Promise polyfill from Hermes if it is available (according to https://github.com/facebook/react-native/issues/35363#issuecomment-1335298726) resulting in Promise.allSettled still missing when using Hermes. This will be fixed in react-native@0.71.x (https://github.com/facebook/hermes/issues/766#issuecomment-1340085132).

The workaround suggested in https://github.com/facebook/hermes/issues/766#issuecomment-1182737719 will unblock current versions of React Native.

The workaround is clearly not a great experience, so we will be looking into a proper fix.

@jeromeheissler and @imdkbj I noticed you are both calling DataStop.stop before DataStore.clear. Can you try just calling DataStore.clear? and let me know if the issue persists?
