Hi! I'm getting an issue with the ktor client, when I try to make a post request, throws a rare error:

Copy code

override suspend fun addLocation(location: Location): Unit = <http://client.post|client.post> {
        path(LOCATION)
        body = location
    }

It throws

Copy code

java.lang.ClassCastException: com.sergiocasero.model.Location cannot be cast to io.ktor.client.call.HttpClientCall

My first impression was a problem with the serializer, but

Copy code

override suspend fun getLocation(parent: Int): Location =
            client.get<Location> { path("$LOCATION/$parent") }

works perfect, the model is quite simple:

Copy code

@Serializable
data class Location(
        val id: Int,
        val parentId: Int,
        val name: String
)

Any suggestions?

Hi @Sergio Casero. Could you provide client configuration? The solution depends on what serialization feature do you use.

I use JsonFeature with kotlin serialization

@e5l

Copy code

private val client = HttpClient {
        install(JsonFeature) {
            serializer = KotlinxSerializer()
        }
    }

Did you test all platforms? It looks like the native should work only with update?
