使用图API在Azure Active Directory中创建应用程序失败

我正在尝试使用Azure Active Directory Graph API（带有Azure GraphClient nuget包）在Azure AD中创建新应用程序。

我已经使用现有的AAD应用程序进行了身份验证，因此我可以对目录进行写访问。

但是，当创建新的应用程序对象时，Azure Graph API返回此错误：

{"odata.error": {
  "code":"Request_BadRequest",
    "message": {
      "lang":"en",
      "value":"Property  value cannot have duplicate id or claim values."
    },
    "values":
      [{
        "item":"PropertyName",
        "value":"None"
       },
       {
         "item":"PropertyErrorCode",
         "value":"DuplicateValue"
       }
     ]
   }
 }

它没有说明哪个属性有重复的id或声明值——错误消息中有两个空格，就好像名称丢失了一样。

创建应用程序对象的代码如下：

var appname = "Test Application create " + DateTime.Now.Ticks;
var application = new Application()
        {
            AvailableToOtherTenants = false,
            DisplayName = appname,
            ErrorUrl = null,
            GroupMembershipClaims = null,
            Homepage = "http://www.domain.com",
            IdentifierUris = new List<string>() {{"https://domain.com/"+ appname } },
            KeyCredentials = new List<KeyCredential>(),
            KnownClientApplications = new List<Guid>(),
            LogoutUrl = null,
            Oauth2AllowImplicitFlow = false,
            Oauth2AllowUrlPathMatching = false,
            Oauth2Permissions = new List<OAuth2Permission>()
            {
                {
                    new OAuth2Permission()
                    {
                        AdminConsentDescription =
                            $"Allow the application to access {appname} on behalf of the signed-in user.",
                        AdminConsentDisplayName = $"Access {appname}",
                        Id = Guid.NewGuid(),
                        IsEnabled = true,
                        Type = "User",
                        UserConsentDescription =
                            $"Allow the application to access {appname} on your behalf.",
                        UserConsentDisplayName = $"Access {appname}",
                        Value = "user_impersonation"
                    }
                }
            },
            Oauth2RequirePostResponse = false,
            PasswordCredentials = new List<PasswordCredential>(),
            PublicClient = false,
            ReplyUrls = new List<string>(),
            RequiredResourceAccess = new List<RequiredResourceAccess>(),
            SamlMetadataUrl = null,
            ExtensionProperties = new List<ExtensionProperty>(),
            Manager = null,
            ObjectType = "Application",
            DeletionTimestamp = null,
            CreatedOnBehalfOf = null,
            CreatedObjects = new List<DirectoryObject>(),
            DirectReports = new List<DirectoryObject>(),
            Members = new List<DirectoryObject>(),
            MemberOf = new List<DirectoryObject>(),
            Owners = new List<DirectoryObject>(),
            OwnedObjects = new List<DirectoryObject>()
  };
await client.Applications.AddApplicationAsync(application);

我是不是错过了一处房产？似乎没有任何非唯一的属性，并且应用程序是用唯一的名称创建的。

var appname = "Test Application create " + DateTime.Now.Ticks;
var application = new Application()
        {
            AvailableToOtherTenants = false,

            ErrorUrl = null,
            GroupMembershipClaims = null,
            Homepage = "http://www.domain.com",
            IdentifierUris = new List<string>() {{"https://domain.com/"+ "Test" } },// CHANGED LINE
            KeyCredentials = new List<KeyCredential>(),
            KnownClientApplications = new List<Guid>(),
            LogoutUrl = null,
            Oauth2AllowImplicitFlow = false,
            Oauth2AllowUrlPathMatching = false,

            {
