使用用户名和密码连接 示例代码
const Client = require('ssh2-sftp-client');
module.exports = class SFTPClient {
#sftpClient;
constructor() {
this.#sftpClient = new Client();
}
async connect(options) {
try {
return this.#sftpClient.connect(options);
} catch (err) {
return null;
}
}
}
连接最初运行正常，但现在 lambda 函数失败，而 ECS 实例继续正常运行。
这是来自 Lambda 的详细日志

我们也尝试过使用 Node v20 和 ssh2 v1.16.0，但也失败了。
