Hello This is my configuration ``` client HttpClient Apache install JsonFeature serializer = KotlinxSerializer Json ignoreUnknownKeys = true server install ContentNegotiation kotlinx serialization json Json ignoreUnknownKeys = true gson setPrettyPrinting ``` and this is a sample request ```val response = client get lt List lt Event gt gt <http localhost 8080>$ application locationToUrl EventsApi body = contentType ContentType Application Json ``` and this is the output ```invalid 415 Unsupported Media Type Text ``` But if I uncomment `gson setPrettyPrinting ` it works Shouldn t `kotlinx serialization json Json` be enough thinking face

//client
HttpClient(Apache) {
    install(JsonFeature) { serializer = KotlinxSerializer(Json { ignoreUnknownKeys = true }) }
}

//server
install(ContentNegotiation) {
        kotlinx.serialization.json.Json { ignoreUnknownKeys = true }
//        gson { setPrettyPrinting() }
    }

and this is a sample request:

val response = client.get<List<Event>>("<http://localhost:8080>${application.locationToUrl(EventsApi())}") {
    body = ...
    contentType(ContentType.Application.Json)
}

and this is the output:

invalid: 415 Unsupported Media Type. Text: ""

But if I uncomment

gson { setPrettyPrinting() }

it works… Shouldn’t

kotlinx.serialization.json.Json

be enough? 🤔

@Rustam Siniukov I’m also facing problems with

@SerialName

I don’t if its related, but the SS can parse it (when it communicates for instance with Google Api or any other service), but the web app can’t (it shows null) 🤔

found it…

install(ContentNegotiation) {
    json(kotlinx.serialization.json.Json {
        ignoreUnknownKeys = true
        prettyPrint = true
    })
}

instead of:

install(ContentNegotiation) {
        kotlinx.serialization.json.Json {ignoreUnknownKeys = true }
    }
