Unresolved reference: responsePipeline in ktor

Question

Hey I am working in ktor. I am following this answer. I want to use responsePipeline on my androidMain. But I am getting error Unresolved reference: responsePipeline. Actually I created my HttpClient with OkHttp in my androidMain. I don't know why I cannot use in my file. Can someone please guide me.

androidMain

actual fun httpClient(config: HttpClientConfig<*>.() -> Unit) = HttpClient(OkHttp) {
    responsePipeline.intercept(HttpResponsePipeline.Transform) {
    }
    config(this)
    install(Logging) {
        logger = Logger.SIMPLE
        level = LogLevel.BODY
    }
}

commonMain

expect fun httpClient(config: HttpClientConfig<*>.() -> Unit = {}): HttpClient

Error

responsePipeline is a property of HttpClient class, and you are trying to access it on an instance of HttpClientConfig.

Lamda of HttpClient(OkHttp) returns an object of type HttpClientConfig which doesn't have a property named reponsePipeline.

To use responsePipeline you have to create an instance of HttpClient, and after that you can use it.

You can create a method which returns your configured httpClient

fun createHttpClient(config: HttpClientConfig<*>.() -> Unit): HttpClient {
    val httpClient = HttpClient(OkHttp) {
        config(this)
        install(Logging) {
            logger = Logger.SIMPLE
            level = LogLevel.BODY
        }
    }
    httpClient.responsePipeline.intercept(HttpResponsePipeline.Transform) {

    }
    return httpClient
}

Assign this to the actual definition.

actual fun httpClient(config: HttpClientConfig<*>.() -> Unit) = createHttpClient(config)
