Watson Unity SDK suddenly stopped working

Watson Unity speech recognition has suddenly stopped working. It keeps logging an error:

[03/05/2019 17:39:37][SpeechToText.OnListenMessage()][ERROR] Error: <2019-03-05 17:39:37,542 api/src/rapi_common.cc:127>    RD_ERROR    RAPI: "RReco" -> "settings" -> "nbest_size" -> Integer 0 is lower than 1.

This is from the Speech Sandbox example streaming scene, which was working fine until now. Has something changed about the service?

apparently there is some bug in the service, but this is a quick fix for it from the Watson developer community -slack workspace. After creating the credentials and instantiating the service, set MaxAlternatives to 1

_service = new SpeechToText(credentials);
_service.MaxAlternatives = 1; //add this line

this fixes the problem, at least for now. Also make sure that MaxAlternatives doesn't get changed back to 0 later in the script.
