Azure Serverless Endpoint创建API调用失败，请求解析出错求助

我正尝试按照Azure官方文档创建Serverless Endpoint，先后使用API版本2024-04-01和2024-04-01-preview均未成功。通过Azure控制台可正常创建该资源（已测试多个模型），但API始终返回模糊错误。

尝试过无数种请求体变体，曾收到缺少必填属性或负载格式错误的提示，当前当请求体看似完全符合文档要求时，出现如下错误：

{
  "error": {
    "code": "UserError",
    "message": "Error when parsing request; unable to deserialize request body",
    "details": [],
    "additionalInfo": [
      {
        "type": "ComponentName",
        "info": {
          "value": "managementfrontend"
        }
      },
      {
        "type": "Correlation",
        "info": {
          "value": {
            "operation": "128dfO*****IDc15c",
            "request": "3c447*****IDb757"
          }
        }
      },
      {
        "type": "Environment",
        "info": {
          "value": "swedencentral"
        }
      },
      {
        "type": "Location",
        "info": {
          "value": "swedencentral"
        }
      },
      {
        "type": "Time",
        "info": {
          "value": "2024-06-19T17:04:26.5506093+00:00"
        }
      }
    ]
  }
}

我怀疑请求体存在问题，但基于文档尝试了所有能想到的属性值组合仍未解决。以下是最后尝试的请求体：

{
    "properties": {
        "authMode": "Key",
        "contentSafety": {
            "contentSafetyStatus": "Disabled"
        },
        "modelSettings": {
            "modelId": "azureml://registries/azureml/models/mistralai-Mistral-7B-Instruct-v01/versions/10"
        }
    },
    "location": "swedencentral",
    "kind": "ServerlessEndpoint",
    "identity": {
        "type": "None"
    }
}

注意：API示例中的identity字段无法使用，系统提示仅支持None值。

已尝试在Node运行时、Postman、Microsoft Learn UI等多个平台发送请求，并测试了多种负载变体，恳请提供相关解决思路！
