我正在尝试使用 Lookback API 获取 PortfolioItem/Feature 的 PreliminaryEstimateValue，但它总是为空。并且 PreliminaryEstimate 也无法根据响应的错误消息进行 Hydrated。
PreliminaryEstimateValue 不应该使用 Lookback API 正确返回吗？
WSAPI 调用虽然工作正常。
要求：
{
"find": {
"_ProjectHierarchy": 90681998188,
"_TypeHierarchy": "PortfolioItem/Feature",
"Release": {"$in": [131091429492]},

},
"fields": [ "Name", "FormattedID", "PreliminaryEstimateValue", "PreliminaryEstimate", "State"],
"hydrate" : ["State", "PreliminaryEstimate"]
}
回复：
