Question: I have a React Native application that I recently updated.
However, on the majority of my modules, I have this error:

`#<WeakSet> could not be cloned.`

For example, on the module : `@react-native-mapbox-gl`
When I launch my application, I get the error :

`node_modules\@react-native-mapbox-gl\maps\javascript\modules\snapshot\snapshotManager.js: #<WeakSet> could not be cloned.`

I also have it on my react-native-vector-icons module.

Is this a common problem?

Thank you!

Answer: 
1. stop metro
2. reset repo
3. reinstall node\_packages

Try deleting `node_modules` and reinstall with `npm install` or `yarn install` again, and then:

**IOS:**

1. `pod update SDWebImageWebPCoder`
2. `pod install --repo-update`
3. `build project in Xcode`

**Android:**

1. `Open in Android Studio` and `Refresh Gradle Dependencies`.
2. `build project in Android Studio`
