Então, eu estou tentando criar uma função aws lambda, para fazer login em uma instância e fazer algumas coisas. E o script funciona bem fora do lambda, mas quando o empacotamos usando as mesmas instruções destehttps://aws.amazon.com/blogs/compute/scheduling-ssh-jobs-using-aws-lambda/ isso não funciona. Lança este erro.
