AWS lambda 中未捕获的异常 javascript

Question

我正在尝试通过 lambda 从 Amazon LEX 中引出一个意图，但我收到了调用未捕获异常的错误。感谢您的帮助，我的代码如下：

'use strict';

exports.handler = (event, context, callback) => {
  const sessionAttributes = event.sessionAttributes;
  const slots = event.currentIntent.slots;
  const intention = slots.Intention

  {
    let response = {
      sessionAttributes: event.sessionAttributes,
      dialogAction: {
        type: "ElicitIntent",
        message: {
          contentType: "PlainText",
          content: `Would you like to do A or B? `
        }

      }
    }
    callback(null, response);
  }
}

“未捕获的异常”错误通常意味着没有为特定类型的输入提供响应。在您的情况下，回调未到达。

只需删除多余的花括号组（我已将其注释掉）：

'use strict';

exports.handler = (event, context, callback) => {
  const sessionAttributes = event.sessionAttributes;
  const slots = event.currentIntent.slots;
  const intention = slots.Intention

//}                                             <--remove this
    let response = {
      sessionAttributes: event.sessionAttributes,
      dialogAction: {
        type: "ElicitIntent",
        message: {
          contentType: "PlainText",
          content: `Would you like to do A or B? `
        }

      }
    }
    callback(null, response);
//}                                              <--and remove this
}
