我正在尝试为Alexa制作一个简单的问答游戏，其中向用户呈现两个事件并试图猜测第一个第二个事件在第二个事件之前或之后发生。
游戏需要填充一个名为“答案”的插槽。 我的问题是我的DialogElicitSlot（）方法导致错误，Alexa无法读出响应。
任何帮助都表示赞赏，如果某人有一个类似的东西（使用C＃）也会很棒：）

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
}
}
}
此外 - 如果有人能告诉我如何使用代码使插槽成为必需值，我将非常感激。
