[Bug]: Exception in Hostfunction: <unknown>

[jeroenburgers]

What happened?

We are trying to update React Native from 0.75.* to 0.77.1. When we open the app in the simulator we receive an error message from the OneSignal SDK.

Current react native: 0.77.1
Current One Signal SDK: 4.5.4

Steps to reproduce?

It happend when we update to the latest react native version. When we disable `setExternalUserId`, the app works fine. Possible it's a problem with the OneSignal SDK.

We know that are a new version of OneSignal SDK is available, but we are not ready to update to the latest version.

What did you expect to happen?

I expected that the app would run correctly after implementing setExternalUserId from OneSignal.

React Native OneSignal SDK version

4.5.4

Which platform(s) are affected?

• iOS
• Android

Hi @jeroenburgers thanks for reporting. Unfortunately Exception in Hostfunction: <unknown> is not a lot of information for us to go on.

1. Can you share an example of how you use setExternalUserId()? What arguments are you passing, since it has optional parameters?
2. Do you run into errors calling other OneSignal methods? What other OneSignal methods work for you? This could help us narrow down how the setExternalUserId() method is differs.
3. Have you tested on Android? Does any errors appear?

Hi @nan-li,

We have decided to migrate to version 5. It's a waste of time to invest in it. Our approach is always to keep these types of updates separate.

What happened: The app crashed when we used setExternalUserId in an initialized useEffect hook. Without this method, everything works fine.

It might have been due to our AppDelegete file which is replaced with a Swift file (just like the migration guide of react native).

For now, we can close this issue.
