Hello, what is the best way to deal with this error in Kotlin/Native:

kotlin.NotImplementedError: An operation is not implemented: Obtaining serializer from KClass is not available on native due to the lack of reflection. Use .serializer() directly on serializable class.

After adding the .serializer() to Json.stringify I get the following error and I am not sure how to specify the serializer() for the receiving/parsing part:

io.ktor.client.call.ReceivePipelineException: Fail to run receive pipeline

Here’s my request:

val result: ActionResponse = <http://networkHttpClient.post|networkHttpClient.post> {
    url(address)
    body = TextContent(Json.stringify(Event.serializer(), event), contentType = ContentType.Application.Json)
}

Hi @galex, could you catch the exception and print cause?

[galex]

Yup give me a sec

[galex]

@e5l

io.ktor.client.call.ReceivePipelineException: Fail to run receive pipeline
io.ktor.client.call.NoTransformationFoundException: No transformation found: class io.ktor.client.engine.ios.IosHttpResponse -> class 
com.analytics.core.network.model.ActionResponse

I see that I didn’t set up any serializer on the HttpClient(), I am trying that

The exception reporting is fixed in master and will be available in 1.2.0 🙂

[galex]

Ahhhhh sweet!!

[galex]

Is there a snapshot dependency to try that out?

[e5l]

1.2.0-alpha-1 but wo iOS for now.

[galex]

What can I do in the meantime in my code?

[galex]

I can register a mapper right?

[e5l]

Yep, but you have to pass class serializer instead of using method with generic parameter.

[galex]

actual val networkHttpClient: HttpClient
    get() = HttpClient {
        install(JsonFeature) {
            serializer = KotlinxSerializer(Json(encodeDefaults = false)).apply {
                setMapper(Event::class, Event.serializer())
                setMapper(ActionResponse::class, ActionResponse.serializer())
            }
        }
    }

Correct?

[galex]

Till 1.2.0 gets out where this is taken care of automatically, cool :))

@e5l it worked, you rock!
