我正在尝试为 Alexa 制作一个简单的问答游戏，其中向用户展示了两个事件，并尝试猜测第一个第二个事件是在第二个事件之前还是之后发生。
游戏需要填写一个名为“答案”的位置。我的问题是我的 DialogElicitSlot() 方法导致错误并且 Alexa 无法读出响应。
任何帮助表示赞赏，如果有人有类似的工作示例（使用 C#），那也很棒:)

当我测试我的技能时，我得到的回应是
{
"body": {
"version": "1.0",
"response": {
"outputSpeech": {
"type": "PlainText",
"text": "did the previous event happen before, or after next event ?"
},
"directives": [
{
"type": "Dialog.ElicitSlot",
"updatedIntent": {
"name": "nextEvent",
"confirmationStatus": "NONE",
"slots": {
"answer": {
"name": "answer",
"confirmationStatus": "NONE"
}
}
},
"slotToElicit": "answer"
}
],
"shouldEndSession": false
}
}
}
另外-如果有人能告诉我如何使插槽成为从代码中工作的必需值，我将不胜感激。
