Hi, I am developing multiplatform library based on Ktor. Everything works fine until I enable Arxan code protection. With this modification all ktor request fail with exception: java.lang.Exception: com.aaa.aaa.aaa.AAA cannot be cast to io.ktor.client.call.HttpClientCall. Any idea how to fix it?

I experienced similar issue using Gson library. The debug build worked normally, but the release build with code obfuscation caused the problem. And I had to put
@SerializedName
annotations to properties which need to be serialized into json to solve the issue. I'm not sure this relates to your case.

I am not using Gson and everything works fine for proguard enabled builds. Ktor stop working only for binary code protected builds. I will have to use retrofit or other framework instead ktor for android builds…
@e5l Any idea how to fix that? We have temporary solution - our own library which use retrofit for android and ktor for ios, but we would like to use ktor for both.
