The function of SFTP is working locally and it has the correct configuration. The problem is with the logs of Lambda that complains about the configuration I believe by giving me an Error: Timed out while waiting for a handshake.

const config = {
    host: 'ftp.xxxx.at',
    port: '22',
    username: 'SFTP_xxx',
    password: 'xxx9fBcS45',
    MD5_Fingerprint: 'xxx:8f:5b:1a',
    protocol: "sftp",
    algorithms: {
        serverHostKey: ['ssh-rsa', 'ssh-dss']
      }
};


// get file
// get sftp file
// here ....
const get = () => {
    sftp.connect(config).then(() => {
        return sftp.get('./EMRFID_201811210903.csv', null, 'utf8', null);
    }).then((stream) => {
        let body = stream.on('data', (chunk) => {
            body += chunk;
        })
        stream.on('end', () => {

            uploadRFIDsToS3(body)
            // close connection
            sftp.end()
        });
    }).catch((err) => {
        console.log('catch err:', err)
    })
};

I added VPC and Security Group in AWS and I still get the same error. I ran out of ideas of how to fix it.

我想通了。问题是 Lambda 实际上是在没有建立连接的情况下转到另一个函数。所以我所做的就是将等待添加到连接和其他不应相互干扰的功能中才能正常工作。

增加 lambda 函数的超时值。分配更多内存和超时的选项是 aws 中任何 lambda 函数的一些设置
