在 Core 3.1 應用程序中綁定給定患者屬性時出錯（FHIR .net model 作為請求模型）

Question

我有 .net 核心 3.1 web 應用程序，

使用 HL7.Fhir.R4(1.7.0)。

我使用患者 model 作為請求 model，

        [HttpPost]
        public Hl7.Fhir.Model.Patient Create([FromBody] Hl7.Fhir.Model.Patient patient)
        {
            //Use the client to create patient
            return patient;
        }

這是一個請求 model，

{
    "ResourceType": "Patient",
    "Active": true,
    "Name": [
        {
            "Use": 1,
            "Family": "Kirk",
            "Given": [
                "Darshana"
            ]
        },
        {
            "Use": 0,
            "Given": [
                "Jim"
            ]
        }
    ],
    "Gender": 1,
    "BirthDate": "1994-08-25"
}

出現以下錯誤：

我讀了代碼，它正在使用 Linq.Select 將值設置為其他 object 失敗。

如何綁定Given屬性？ 請幫忙。

也許這可以幫助某人或從事此工作的人可以驗證或建議他們是否擁有某些東西，

我創建了ResourceJsonInputFormatter和ResourceJsonOutputFormatter ，在啟動時注冊格式化程序，最終使用 FhirSerializer 序列化 API 請求和響應。 現在它工作正常。
