我正在尝试构建一个演示 Alexa Skill，其中我使用 Customer Profile API 来获取客户详细信息，例如电子邮件等，然后我想将电子邮件 ID 保存到 dynamoDb 。我已按照文档中的所有说明进行操作，但无法使其正常工作。请查看我的代码并告诉我我做错了什么。任何帮助或新鲜的观点表示赞赏。

return new Promise((resolve, reject) => {
const params = {
TableName: tableName,
Item: {
'email' : email,
'userId': userID

docClient.put(params, (err, data) => {
if (err) {
console.log("Unable to insert =>", JSON.stringify(err))
return reject("Unable to insert");
}
console.log("Saved Data, ", JSON.stringify(data));
resolve(data);
