Alexa skill testing error: Error handled: Cannot read property 'value' of undefined
问题
Here is the translated code:
请帮助我，如果有人解决了问题，以下是我的 Lambda 函数代码。
当我在 `exports.handler` 函数中注释掉所有函数并执行/测试单个函数时，它能正常工作，但如果启用所有函数，我会收到错误：**错误处理：无法读取未定义的属性 "value"**

检查你的代码中是否存在查找 `someObject.someNestedProperty.value` 的情况。
我怀疑你在意图中定义的插槽值与你的 `model/some-LANG.json` 文件中的定义不同。尝试在没有 `someNestedProperty` 的情况下访问 `someObject` 中的 `value` 属性将导致错误（例如 `request.intent.slots.PROJECTKEY.value`）。
如果这是一个 Alexa 托管的技能，CloudWatch 日志记录已经内置。打开 **Alexa Developer Console**，编辑你的技能，然后转到 **Code** 选项卡。在左下角，你应该看到一个名为 **Logs: Amazon CloudWatch** 的链接。你可以使用简单的 `console.log()` 语句记录任何你想要的内容。
此外，请注意 `ask-sdk-core` npm 包包含用于获取 slotValues（以及其他伟大工具）的辅助方法。有关更多信息，请参阅此链接：https://developer.amazon.com/en-US/docs/alexa/alexa-skills-kit-sdk-for-nodejs/utilities.html

Check all of your code for instances where you are looking for `someObject.someNestedProperty.value`.
I suspect that your slot values in your Intents are not the same as defined in your `model/some-LANG.json` file. Trying to access `value` property from `someObject` without a `someNestedProperty` will cause your error (i.e. `request.intent.slots.PROJECTKEY.value`).
If this is a Alexa-hosted skill, CloudWatch logging is built right in. Open the **Alexa Developer Console**, edit your skill, then go to the **Code** tab. On the bottom left, you should see a link for **Logs: Amazon CloudWatch**. You can log anything you want with a simple `console.log()` statement.
Also, be aware that the `ask-sdk-core` npm package contains helper methods to get slotValues (among other great tools). For more information, see this link: https://developer.amazon.com/en-US/docs/alexa/alexa-skills-kit-sdk-for-nodejs/utilities.html

谢谢大家的建议和及时回应。现在问题已解决，解决方法是addRequestHandlers方法将按顺序执行方法，即使您执行/触发第三个处理程序，它也将执行第一个和第二个，然后转到第三个。这里的问题是，当您从Alexa触发第三个处理程序命令时，它将传递与第三个处理程序话语相关的插槽值，因此具有插槽值的第一个和第二个处理程序无法解析并失败。因此，我在那里加入了一个条件以跳过第一个和第二个处理程序的执行，这样就解决了问题。
<details>
<summary>英文:</summary>
Thanks all for your suggestions and prompt response.
Now the issue is resolved and the solution is the addRequestHandlers method will execute methods sequentially even if you execute/trigger third handler it will execute 1st and 2nd and goes to 3rd one. Here the issue is when you trigger a 3rd handler command from alexa it will passs the slot values related to the 3rd handler utterance and hence the 1st and 2nd haldler having slot values are not able to resolve and failed. so i put a condition overthere to skip 1st and 2nd handler execution and it worked.
