IOS crash while handling event

[Legion2]

I'm getting app crashes while sentry is handling some exception.

Uncaught Kotlin exception: kotlin.ClassCastException: class kotlin.Int cannot be cast to class kotlin.Long
The stacktrace indicates that it happens in toKmpSentryException kfun:io.sentry.kotlin.multiplatform.extensions#toKmpSentryException__at__cocoapods.Sentry.SentryException(){}io.sentry.kotlin.multiplatform.protocol.SentryException + 723
I think it happens at this line:

sentry-kotlin-multiplatform/sentry-kotlin-multiplatform/src/commonAppleMain/kotlin/io/sentry/kotlin/multiplatform/extensions/SentryExceptionExtensions.kt

Line 10 in b79cc79

threadId = threadId as Long?

Thanks for the issue! This should definitely not be an unsafe cast.

Do you maybe have a minimal reproducible example of when this happens?

@buenaflor iOS uses NSNumber so it can be Int and/or Long, we need to do a safe cast here.

fun getFileLocation(fileName: String): NSURL {
    return NSBundle.mainBundle.URLForResource(fileName, "txt")
        ?: error("Could not find $fileName")
}

to reproduce the issue, you can call this kotlin function from Swift with an non existing file name then it will create an exception, which will then cause a different exception in sentry.
