Bug Android Ads SDK SDKErrorHandler coroutine error crash

This seems to occur during an unknown network error. The SDK tries to catch the unhandled error and send metrics (although I don't even have those enabled), but it fails on a non-null conversion.

The relevant JavaDoc for the failure is: https://docs.oracle.com/javase/8/docs/api/java/lang/StackTraceElement.html#getFileName--

It says "or null if this information is unavailable.", so this case is expected and this line should be changed to `className: String?`: https://github.com/Unity-Technologi...a/com/unity3d/services/SDKErrorHandler.kt#L17

I think you can reproduce this by using Pi-hole or similar network-level ad blocking software, but I don't think a reproduction is necessary. I've pointed to a line of code in direct contradiction of the JavaDoc for a platform API.

 

Hello, I'm having this issue in Unity Ads SDK 4.7.1.
Do you have an update when the Unity Ads SDK 4.9.0 will be released?
Is there a workaround for this issue or an older version that is safe to use?

 

I noticed that the SDK 4.9.0 was released yesterday, could you confirm the fix for the issue reported here is included in the changelog, please? https://docs.unity.com/ads/en-us/manual/Changelog#Version_4.9_-_released_2023-09-27
