使用Xero Assets API无法设置Depreciation Start Date问题求助

我通过Xero Assets API创建固定资产（未使用SDK），所有字段均正常生效，唯独Depreciation Start Date在Xero UI中显示为空。

发送的API请求体 #

{
  "assetName": "Asset name",
  "assetNumber": "CA-46987", 
  "serialNumber": "",
  "purchasePrice": 432,
  "purchaseDate": "2024-03-06T15:04:30.373",
  "bookDepreciationSetting": {
    "depreciationMethod": "StraightLine",
    "averagingMethod": "FullMonth",
    "effectiveLifeYears": 5,
    "depreciationCalculationMethod": "Life"
  },
  "bookDepreciationDetail": {
    "depreciationStartDate": "2024-03-07"
  }
}

API返回响应 #

{
  ...
  "bookDepreciationSetting": {
    "depreciableObjectId": "0965dc9e-3a5a-46f0-aac9-d7b7f0a466a5",
    "depreciableObjectType": "Asset",
    "bookEffectiveDateOfChangeId": "98108fe1-9eaa-4145-b660-4f36ca2a5418",
    "depreciationMethod": "StraightLine",
    "averagingMethod": "FullMonth",
    "effectiveLifeYears": 5,
    "depreciationCalculationMethod": "None"
  },
  "bookDepreciationDetail": {
    "depreciationStartDate": "2024-03-07T00:00:00",
    "priorAccumDepreciationAmount": 0,
    "currentAccumDepreciationAmount": 0,
    "currentCapitalGain": 0,
    "currentGainLoss": 0
  },
  "taxDepreciationSettings": [],
  "taxDepreciationDetails": [],
  "canRollback": true,
  "accountingBookValue": 432,
  "taxValues": [],
  "isDeleteEnabledForDate": true
}

从响应可见，depreciationStartDate已被正确处理为2024-03-07T00:00:00，并非简单回显我发送的日期部分2024-03-07，但在Xero UI中该字段仍为空，其余信息均正常填充。

已尝试的日期格式 #

• 2024-03-07
• 2024-03-07T00:00:00
• 2024-03-07T00:00:00.000
• 完整ISO日期格式

以上格式均无效。

补充测试 #

当使用"\/Date(1709769600)\/"格式发送日期时，API响应中bookDepreciationDetail里的depreciationStartDate字段直接被忽略：

...
"bookDepreciationDetail": {
  "priorAccumDepreciationAmount": 0,
  "currentAccumDepreciationAmount": 0,
  "currentCapitalGain": 0,
  "currentGainLoss": 0
},
...

请问这是API Bug还是我遗漏了必要参数？
