Azure API管理重写招摇过市文件

我正在尝试将一个OpenAPI 3.0.1文件上载到APIM，由于某些原因，该文件在上载后看起来有所不同。由于某些原因，APIM上的“format”属性被删除。此外，一些输入参数正在无明显原因地移动。在此问题上的任何帮助都将不胜感激。我已经在这上面呆了一段时间了

我想知道的是，APIM是否有自己的OpenAPI文件规则集，是否有办法更改我的文件，使其不被APIM修改

        "summary": "Gets a list of available appointment slots",
        "description": "You must create an appointment first",
        "operationId": "ServiceAppointment_GetAvailableSlots",
        "parameters": [
          {
            "name": "id",
            "in": "path",

            "required": true,
            "schema": {

            }
          },
          {

            "in": "query",
            "description": "Format - date-time (as date-time in RFC3339)",
            "schema": {
              "type": "string",
              "format": "date-time"  //format disappears on APIM
            }
          }
        ],
