在尝试将lambda连接到documentdb时得到以下错误日志。

}lambda的VPC与documentdb实例相同。nodejs代码在本地运行时成功连接实例，但在lambda中有问题。
const { MongoClient } = require('mongodb');
exports.handler = async(event, context) => {
console.log("insideHandler");
const uri = 'mongodb://username:password@sample-dev-01-instance1.abcde.us-east-1.docdb.amazonaws.com:27017';
const client = new MongoClient(uri, {
useNewUrlParser: true,
ssl: true,
tlsCAFile: `rds-combined-ca-bundle.pem`, //Specify the DocDB; cert
retryWrites: false
});
try {
await client.connect();
console.log("connect successfully");
return {
statusCode: 200,
body: JSON.stringify({ message: 'connect successfully' })
}
}
catch (e) {
console.error(e);
}
};enter code here
EAI_AGAIN是DNS查找超时错误，意味着它是网络连接错误或代理相关错误。您能确认Lambda函数是否使用与DocumentDB集群相同的安全组吗?
