QnAMaker QueryResult Missing Context Property

Question

I'm working on adding follow up prompts to QnAMaker responses.

var answers = await qnaService.GetAnswersAsync(stepContext.Context, null, null);
var prompts = answers[0].Context?.morecodehere() <---  Context not defined. 

answers is resolved as QueryResult[]

The documentation, samples, and SO question indicate that there is a Context property on the QueryResult object; however, my project's QnAResult from the Virtual Assistant Template does not.

I'd like to be able to follow the samples's way of accessing follow-up prompts using adaptive cards.

My question is whether or not I have something outdated or if it is more likely that I have a configuration issue. Could this be as simple as creating a new QueryResult model to use?

Sample from Microsoft's sample library:

...

 var query = inputActivity.Text;           
 var qnaResult = await _qnaService.QueryQnAServiceAsync(query, (QnABotState)oldState);
 var qnaAnswer = qnaResult[0].Answer;
 var prompts = qnaResult[0].Context?.Prompts;

if (prompts == null || prompts.Length < 1)
 {
    outputActivity = MessageFactory.Text(qnaAnswer);
 }

        [JsonProperty("answer")]
        public string Answer { get; set; }

        [JsonProperty("score")]
        public float Score { get; set; }

        [JsonProperty(PropertyName = "metadata")]
        public Metadata[] Metadata { get; set; }

        [JsonProperty(PropertyName = "source")]
        public string Source { get; set; }

        [JsonProperty(PropertyName = "id")]
        public int Id { get; set; }
    }
}
