Why

expectSuccess = false

not working at 1.2.2? On Ktor multiplatform I catch Platform exception
I tried the following options:

HttpClient {
            expectSuccess = false

and

HttpClient {
HttpResponseValidator {
                validateResponse {response ->
                    if (response.status.value!=200) {
                        throw ResponseException(response)
                    }
                }

            }

And

ResponseException

not catched. Only

Exception

not Solved 😞
