How to send post form-data with file and data using Azure Api Management?

Question

I want to create a post request on Azure API Management with a form-data format. I must send a file and data in body to an url but don't see how to send both.

I get http code from postman where it works: request in postman

I don't find way to send my post request with file and data. When I tried to send with one of two I get the response:

I tried to put a boundary in request header and body but I had the same error. I have the following body: Body content

OpenAPI v3 support in Azure API Management includes fixes and improvements to the preview functionality—for example, it enables support for multipart/form-data content type.

In OpenAPI 3.0, request body (including form data) is defined using the requestBody keyword instead of in: formData parameters.

"paths": {
  "/api/rmt-create-request": {
    "post": {
      "tags": [
        "RMT APIs"
      ],
      "description": "Return newly created request data",
      "operationId": "create-new-rmt-request",
      "requestBody": {
        "content": {
          "multipart/form-data": {    // or  "application/x-www-form-urlencoded" - depending on what you need
            "schema": {
              "type": "object",
              "properties": {
                "rootNodeName": {
                  "type": "string",
                  "description": "Root node class name for item"
                }
              }
            }
          }
        }
      }
    }
  }
}
