Cosmos DB： 响应状态代码不指示成功： BadRequest （400）;子状态： 1001;原因： （）;

Question

我正在使用Cosmos DB存储库并尝试为下面的对象添加新项目。

[Container(nameof(Notifications))]
    [PartitionKeyPath("/UserUUId")]
    public class Notifications : Item
    {
        [JsonProperty(PropertyName = "RequestID", Order = 2)]
        public string RequestID { get; set; }

        [JsonProperty(PropertyName = "NotificationType", Order = 3)]
        public int NotificationType { get; set; }

        [JsonProperty(PropertyName = "SubType", Order = 4)]
        public string SubType { get; set; }

        [JsonProperty(PropertyName = "UserUUId", Order = 5)]
        public string UserUUId { get; set; }

        [JsonProperty(PropertyName = "Payer", Order = 6)]
        public string Payer { get; set; }

        [JsonProperty(PropertyName = "PayerName", Order = 7)]
        public string PayerName { get; set; }

        [JsonProperty(PropertyName = "Account", Order = 8)]
        public string Account { get; set; }

        [JsonProperty(PropertyName = "AccountName", Order = 9)]
        public string AccountName { get; set; }

        [JsonProperty(PropertyName = "Created", Order = 10)]
        public DateTime Created { get; set; }

        [JsonProperty(PropertyName = "Updated", Order = 11)]
        public DateTime? Updated { get; set; }

        [JsonProperty(PropertyName = "Status", Order = 12)]
        public int Status { get; set; }

        [JsonProperty(PropertyName = "MetaData", Order = 13)]
        public Dictionary<string, string> MetaData { get; set; }

        protected override string GetPartitionKeyValue() => UserUUId;
    }

这是我添加新项目的代码代码：

public class UINotificationPublisher : IUINotificationPublisher
{

   private readonly IRepository<Notifications> _uiNotificationsRepository;

    public UINotificationPublisher(
        IRepositoryFactory factory
    
        )
    {
        _uiNotificationsRepository = factory.RepositoryOf<Notifications>();

    }

    public async Task PublishAsync(IEnumerable<UserSubscriptions> userSubscriptions, CardGroupEvent @event, ILogger logger)
    {
        try
        {
            var uiSubscriptions = userSubscriptions
                .Where(x => x.Events.Any(y => y.EventType == (int)EventType.CARD_GROUP_CHANGED && y.Channels.Contains((int)ChannelType.UI)));

            if (uiSubscriptions.Any())
            {
                logger.LogInformation($"UI notification subscriptions found, requestID:{@event.RequestID}");

                List<Notifications> uiNotifications = new List<Notifications>();

                foreach (var item in uiSubscriptions)
                {
                    logger.LogInformation($"creating UI notification for UUID:{item.UUID}. requestID:{@event.RequestID}");

                    uiNotifications.Add(CreateItemAsync(item, @event));

                    logger.LogInformation($"successfully created UI Notification for UUID:{item.UUID}: {@event.RequestID}");
                }
                await _uiNotificationsRepository.CreateAsync(uiNotifications);
            }
            else
                logger.LogInformation($"No UI notification subscriptions found: requestID:{@event.RequestID}");
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

    private Notifications CreateItemAsync(UserSubscriptions userSubscription, CardGroupEvent @event)
    {
        Notifications notifications = new Notifications
        {
            Id = Guid.NewGuid().ToString(),
            Created = DateTime.UtcNow,
            RequestID = @event.RequestID,
            NotificationType = (int)EventType.CARD_GROUP_CHANGED,
            SubType = @event.EventSubType,
            UserUUId = userSubscription.UUID,
            Payer = @event.PayerNumber,
            PayerName = @event.PayerName,
            Account = @event.AccountNumber,
            AccountName = @event.AccountName,
            MetaData = GetMetaData(@event),
            Status = (int)NotificationStatus.UnRead

        };
      
        return notifications;
        
    }

    private Dictionary<string, string> GetMetaData(CardGroupEvent @event)
    {
       

        var metaData = new Dictionary<string, string>();
     
        metaData.Add(nameof(@event.AccountNumber), @event.AccountNumber);
        metaData.Add(nameof(@event.AccountName), @event.AccountName);
      
        return metaData;
    }
}

Cosmos DB Respository CreateAsync：

插入新项目时出现以下异常：

"响应状态码不表示成功：BadRequest（400）；Substatus：1001；ActivityId：68af0c72-ff2d-4055-8898-b94a08f18ead；原因：（）；"

这在错误请求的故障排除文档中有所介绍

带有此错误的响应意味着您正在执行一个操作并传递一个与预期属性的文档正文值不匹配的分区键值。如果集合的分区键值路径 /myPartitionKey，则文档具有一个名为my分区键值的属性，其值与调用SDK方法时提供的分区键值不匹配。

您没有共享调用Cosmos DB SDK的代码（只是调用一些存储库对象），因此很难指向正确的代码，但如果您正在调用例如：

container.CreateItem(<item>, new PartititionKey(pkValue))

此错误意味着您传递的新分区键 （pkValue） 不正确，它不是项目中容器的分区键定义属性的值。

代码可能假设分区键定义已启用（例如，/Payer），但容器的实际分区键定义是另一个（例如，\id）。
