Consider using ```io ktor ktor client serialization``` in common and remove platform dependencies

wellingtoncosta · Answer

< e5l> I removed the platform dependencies but the `KotlinxSerializer` is still missing

wellingtoncosta · Answer

What do you mean by small reproducer

e5l · Answer

I mean the project with configuration and code snippet

e5l · Answer

Cause I can t reproduce it locally

wellingtoncosta · Answer

Ok I have the following configuration ```private val json = Json ignoreUnknownKeys = true useArrayPolymorphism = true isLenient = true private val instance = HttpClient configureJson configureLogging configureDefaultRequest configureResponseValidation private fun HttpClientConfig lt gt configureJson install JsonFeature serializer = KotlinxSerializer json ``` And the current dependencies are ``` common implementation io ktor ktor client core 1 4 0 implementation io ktor ktor client json 1 4 0 implementation io ktor ktor client logging 1 4 0 implementation io ktor ktor client serialization 1 4 0 android implementation io ktor ktor client android 1 4 0 ios implementation io ktor ktor client ios 1 4 0 ```

< e5l> any idea

wellingtoncosta · Answer

It s so stranger cause the `KotlinxSerializer` is in the source code

This happens for me too Can t use it with Ktor server

Daniel Eke · Answer

Maybe `io ktor ktor client serialization` could be updated in the documentation here <https ktor io docs json feature html> It still says that I need to used the native version That got me a bit confused until I looked up this thread
