Alexa 通知:身份验证令牌无效

Alexa notifications: The authentication token is not valid

Alexa 通知是否可用于开发技能?我在任何地方都看不到任何配置。发送通知时出现此错误。

{
    "message": "The authentication token is not valid.",
    "code": 403
}

,Alexa Skills Kit 中的通知功能尚未普遍可用。任何想要拥有通知功能的人都必须填写 this survey and Amazon team provides more information if they think the skill is qualified to have notifications feature. For more information see this
