A modern programming language that makes developers happier.

kotlinlang

With HttpResponseValidator


fun <T : HttpClientEngineConfig> HttpClientConfig<T>.exceptionHandling() {
    HttpResponseValidator {
        handleResponseExceptionWithRequest { exception, _ ->
            val type = when (exception) {
                is ClientRequestException -> RemoteExceptionType.CLIENT_ERROR
                is ServerResponseException -> RemoteExceptionType.SERVER_ERROR
                is JsonConvertException -> RemoteExceptionType.PARSING_ERROR
                else -> RemoteExceptionType.UNKNOWN
            }
            throw RemoteException(type)
        }
    }

unknown host exception is not possible to catch with this.

Then you can always wrap your request block with run catching
