我正在研究一项Alexa技能（适用于Node.js的ASK-SDK v.2），该技能可以从Airtable数据库执行GET。用户要求输入角色名称，然后技能将对照此数据库进行检查以检索简短的描述。
但是，当我在Skill Builder上进行一些测试时，即使我说出在JSON INPUT中产生ER_SUCCESS_MATCH的角色名称，JSON OUTPUT也会将解析后的值（实际上是任何有效名称）返回为UNDEFINED。无论我查询的字符名称是什么，我都听到的消息是“我在数据库中找不到未定义的字符。”
即使我相信我在代码中提供了正确的API密钥和AirtableGet密钥，我仍然认为该技能无法连接到我的Airtable基地以获得角色名称。此外，我应该在我的AWS Lambda日志上看到一个“ IN AIRTABLE GET”条目，就在IN CHARACTER HANDLER和通常的END RequestID之间，但是到目前为止，我从IN CHARACTER HANDLER跳到了END RequestID，所以Airtable db似乎没有被调用。
这是完整的Index.js代码（减去技能编号，API密钥和角色名称列密钥）。你能发现任何错误吗？预先感谢您的帮助！
