Cognito ListUsers将永远持续下去

嘿,我写了一些代码来下载我的Cognito用户池中的所有用户,但它似乎永远在继续。我很确定我使用的分页标记是正确的。Cognito的UI估计我有大约10000个用户,但是我在我的循环和我的 List 已经超过50000了这是不合理的。

非常感谢您的帮助!

        using (AmazonCognitoIdentityProviderClient provider = AuthorizedClient())
        {
            try
            {
                List<UserType> users = new List<UserType>();
                bool continueListing = true;

                ListUsersResponse response = provider.ListUsers(
                    new ListUsersRequest
                    {
                        UserPoolId = UserPoolId,
                        Limit = 60,
                        AttributesToGet = new List<string>
                        {
                            "email"
                        }
                    });

                users.AddRange(response.Users);
                string paginationToken = response.PaginationToken;
                while (continueListing)
                {
                    response = provider.ListUsers(
                        new ListUsersRequest
                        {
                            UserPoolId = UserPoolId,
                            Limit = 60,
                            PaginationToken = paginationToken,
                            AttributesToGet = new List<string>
                            {
                                "email"
                            }
                        });

                    if (response.Users.Count < 60)
                    {
                        continueListing = false;
                    }
                    else
                    {
                        paginationToken = response.PaginationToken;
                        users.AddRange(response.Users);
                    }
                }

                return users;
            }
            catch (Exception)
            {
                //_session.NotifyUser(Notification.GeneralError());
                //_logger.LogError(e.Message);
            }

            return null;
        }
