我正在使用 boto3 創(chuàng)建一個 IAM 用戶，等到 IAM 用戶被創(chuàng)建，然后更新該用戶的登錄配置文件。我創(chuàng)建用戶的python代碼工作正常，用戶創(chuàng)建成功。IAM 最終是一致的，所以我知道我需要等待用戶被創(chuàng)建，然后我才能用它做任何其他事情，我為此使用了一個服務(wù)員。但是當(dāng)我嘗試更新登錄配置文件時，它出錯說用戶還不存在。所以基本上服務(wù)員并沒有像它應(yīng)該的那樣等待。有誰知道我在這里做錯了什么？import boto3password = 'not_the_real_password'client = boto3.client('iam')# Create the userresponse = client.create_user(    UserName='someuser')# Creating the user works fine. But IAM is eventually consistent, so we have# to wait for the user to be created before we can do anything with it.waiter = client.get_waiter('user_exists')waiter.wait(UserName='someuser')# If the waiter worked correctly, then it should have waited for the user# to be created before updating the login profile.response = client.update_login_profile(    UserName='someuser',    Password=password,    PasswordResetRequired=True)預(yù)期結(jié)果：服務(wù)員應(yīng)該等待 IAM 用戶存在足夠長的時間，然后更新登錄配置文件將按預(yù)期工作。實際結(jié)果：Traceback (most recent call last):  File "add_user.py", line 20, in <module>    PasswordResetRequired=True  File "/home/myuser/.local/lib/python3.6/site-packages/botocore/client.py", line 357, in _api_call    return self._make_api_call(operation_name, kwargs)  File "/home/myuser/.local/lib/python3.6/site-packages/botocore/client.py", line 661, in _make_api_call    raise error_class(parsed_response, operation_name)botocore.errorfactory.NoSuchEntityException: An error occurred (NoSuchEntity) when calling the UpdateLoginProfile operation: Login Profile for User someuser cannot be found.
