在某些情况下，我试图向用户加价订阅（该技能中唯一的高级产品）。但是，发送请求后，Alexa不会跟进，也不会启动加售过程。无法读取加售消息，也没有其他输出（只是静音）。
Lambda函数的处理程序中的Upsell指令
upsell_msg = ("Sorry, noobie! You just reached the daily limit for the Free Subscription! To get access to 10 prices per day, you can upgrade to the amazing Premium Subscription. {} Want to learn more?").format(subscription_pack[0].summary)
handler_input.attributes_manager.session_attributes["lastSpeech"] = upsell_msg
return handler_input.response_builder.add_directive(
SendRequestDirective(
name = "Upsell",
payload = {
"InSkillProduct": {
"productId": subscription_pack[0].product_id,
},
"upsellMessage": upsell_msg,
},
token = "correlationToken")).response
JSON输出

更新：
进一步研究之后，问题似乎出在Upsell指令位于意图处理程序中，该处理程序具有由Alexa处理的对话模型（对话委托策略-自动委派）。
我进行了以下测试：将Upsell指令移至Lambda函数中的另一个Intent处理程序（仅用于测试），并且在触发该Intent时，它可以完美运行。但是，在原始的Intent处理程序（将对话框委托设置为auto的处理程序）中，Upsell请求没有得到Alexa的响应。
