Using Javascript in a browser, when HttpClient.webSocketSession() fails with HTTP 401 error then a generic WebSocketException is throw:

WebSocketException: {"target":{},"type":"error","isTrusted":true}

The same exception is thrown when connection fails because the server is not running.

Is it possible to somehow differentiate among the various errors that can happen when connecting?
Thanks.

I get the NoTransformationFoundException when the server replies with 401 status code:

val client = HttpClient(Js) {
    install(WebSockets)
}
try {
    client.webSocketSession("<https://httpbin.org/status/401>")
} catch (e: Throwable) {
    e.printStackTrace()
}
