Hello! I am trying to use a multiplatform library ...

# ktor

[Daniel Fera]

Hello!
I am trying to use a multiplatform library that uses ktor for requests in an iOS Network Extension target and every time HttpClient is initialized I encounter an EXC_BAD_ACCESS crash in Kotlin_ObjCExport_convertUnmappedObjCObject method
Here is the stack trace:

Note that the same library used in an iOS application target works without issues.
Are there limitations regarding ktor used in iOS Network Extensions?

Can you please check a simple GET request with Ktor (without the library)?
