tseisel · Answer

I just tried this code and it worked fine i m using `ktor client okhttp` and `ktor client gson` on the JVM maybe your problem comes specifically from the `ktor client ios` implementation

Sergioedcigreja · Answer

yeah it only occurs on iOS

Hi < Sergioedcigreja> it s the known problem There is no reflection in `kotlin native` and you have to call `register` method on `KotlinxSerializer` explicitly for now disappointed

Sergioedcigreja · Answer

thats interesting I must be doing something wrong as I cant reference KotlinxSerializer

sure

Sergioedcigreja · Answer

thank you

e5l · Answer

It looks like ` io ktor ktor client serialization $ktor version ` is missing in `commonMain` It would be easier to config with gradle metadata enabled
