Hello,
I'm trying to create a web socket connection in a KMP project as follows but it's giving me this exception: Serializer for class 'DefaultClientWebSocketSession' is not found

Caused by: kotlinx.serialization.SerializationException: Serializer for class 'DefaultClientWebSocketSession' is not found.
Please ensure that class is marked as '@Serializable' and that the serialization compiler plugin is applied.

class WebSocketClientImpl(engine: HttpClientEngine) : WebSocketClient() {

    private val client = HttpClient(engine) {
        install(ContentNegotiation) {
            register(
                ContentType.Text.Html, KotlinxSerializationConverter(
                    Json
                )
            )
        }
        install(WebSockets) {
            contentConverter = KotlinxWebsocketSerializationConverter(Json)
        }
    }

    private var session: WebSocketSession? = null

    override fun getWebSocketEvents(): Flow<List<String>> = flow {
        session = client.webSocketSession {
            url {
                takeFrom("<wss://sl-socket-receive.eu.ngrok.io>")
            }
        }
        session!!.incoming
            .consumeAsFlow()
            .filterIsInstance<Frame.Text>()
        //emitAll(data)
    }

    override suspend fun close() {
        session?.close()
        session = null
    }
}

I have tried multiple things but I'm not able to figure out what's wrong.

If you remove the register call in the ContentNegotiation plugin, the problem disappears?

[Mohammed Akram Hussain]

No, it'll give me another error as the response content-Type is text/html

What is the response from the server?
