我正在使用 aws sdk 并想使用get_command_invocation 方法。这是我根据文档所拥有的：

resp = client.send_command(
    instance_ids: [instance_id],
    document_name: 'AWS-RunShellScript',
    max_concurrency: '1',
    max_errors: '1',
    timeout_seconds: 60,
    parameters:
        { commands:
              [command]
        }
)    

command_id = client.get_command_invocation(
        command_id: resp.command.command_id,
        instance_id: instance_id
    )

使用puts我确定该方法正在接收 command_id 和 instance_id，当我尝试在 aws 控制台上查看它们时，它们都存在。然而我一直遇到：

(Aws::SSM::Errors::InvocationDoesNotExist)

我究竟做错了什么 ？

根据评论。

invocation该问题是由于执行后无法立即使用send_command造成的。

解决方案是在调用之前稍等片刻get_command_invocation。这可以通过一个基本while-type循环来实现，该循环将在继续正常程序流程之前以周期性方式持续拉动调用的可用性。
