CSOM CreateSPAsyncReadJob 保持队列状态

Question

我指的是允许使用 CSOM 在 SharePoint 上创建读取作业的 Migration Asynchronous Read API。我能够成功创建读取作业，但不幸的是，该作业长期以来一直处于队列状态。

函数returns包括UniqueJobID、AzureContainerManifestUri、AzureQueueReportUri和EncryptionKey

通过使用 clientContext.Site.GetMigrationJobStatus 方法，我能够检查始终 returns Queued

的读取作业状态

下面是示例代码供参考：

using (var clientContext = new ClientContext(siteUrl))
{
    clientContext.Credentials = new SharePointOnlineCredentials(userName, password);

    var result = clientContext.Site.CreateSPAsyncReadJob($"{siteUrl}/List/MyList", new AsyncReadOptions { });
    clientContext.ExecuteQuery();

    MigrationJobState state;
    do
    {
        var status = clientContext.Site.GetMigrationJobStatus(result[0].JobId);
        clientContext.ExecuteQuery();
        state = status.Value;
    } while (state == MigrationJobState.Queued);
}

我还尝试连接到 AzureQueueReportUri 队列，该队列包含带有加密内容的邮件。我不确定我们如何解密内容以使其可读。这是示例消息：

{
    "Label": "Encrypted",
    "JobId": "079ece4a-cfd2-4676-a27d-2662beb5bb0a",
    "IV": "RYc+ZA2feX1hnAcVWR1R+w==",
    "Content": "qbjTBbb2N+DkNumLoCJSAAfwj8etDLgjxp+b2T9k03L9WfRJKlFBIZO457q+CbHA+8DHJS7VbPzVMoW6ybo2GxgteTYVP+yVUOPPvz57VGQJyzg2gss+Bsjn73GTWWUfwC/W+oWnEpt8PawZysCjSNf6A4HKZKewkskCshN/pND8ZpevrGt2qq0dTt0NkTIkuYv5AvIP7DSWjdl7nN/W5x4c2nR0sPFqKYom41a4tIqrruzwCDEEjWLFtuXAQ+UN2TMV9PWabRFe9n/P1RHrAJaNU+JjJiJm+lE1dQChz+7OuQoJsYnbjYTbqEE8CnIB0/E0zTrc3zLc6th8MBsKpZJjd31ovqr/Xez6zCnvMKotSdScFtTgQqHxmVDBMfMgi2mm8cKQpdKwRufP/YhaDQlvFkmj2FQN0KAMNxwFBh/MWCVhz5uCJ50CGhChcn4h"
}

我也无法连接 AzureContainerManifestUri blob 容器。它因错误 Authentication Error. Signature did not match.

而失败

任何人都可以指导我如何继续吗？
