[4.0.2] iOS: Argument 2 (RCTResponseSenderBlock) of setExternalUserId must not be null

[diego-paired]

Description:
Since upgrading to 4.0.2 from 4.0.1, the following error appears when calling setExternalUserId:

This error did not happen on 4.0.1, and the typescript definitions mark the second argument as optional.

Environment

react: 17.0.1 => 17.0.1 
react-native: ^0.64.0-rc.2 => 0.64.0-rc.2 

"react-native-onesignal": "^4.0.2"

Howdy Diego,
Thank you for reporting this issue. Can you please provide more information regarding the exact environment?

Also, what does your call look like? Can you please include a code snippet?

From looking at the code, it looks like your issue might be able to be resolved by passing an empty callback for now as a temporary workaround:

()=>{}

We will look to implement a long term fix for this in the future.

Cheers

Faced the same issue when fast-refresh happened, but not every time 🤔 passing empty handler fixing issue for now

Howdy,
This should now be resolved in 4.0.3

Enjoy!
