Problem when adding an api controller method with an IFormFile parameter

See original GitHub issue

Hi,

I tried to add a new method in one of my controller. This method takes an IFormFile parameter As soon as I add this method, there is a new consumes array in swagger.json which only contains the value "multipart/form-data"

Problem is when I generate the ts client, all the methods try to send multipart/form-data

I tried to create a simplified repro project, but I cannot reproduce it 😦 Any idea about the cause?

This is the new controller

    [ApiVersion("1")]
    public class ConfigurationController : ApiControllerBase
    {
        [HttpPost, DisableRequestSizeLimit]
        public void UploadFile(IFormFile file)
        {
        }
    }

swagger.json before I add the controller (there is no consumes array) Note: in my repro project, there is always a consumes array. Do you know what can prevent it to appear?

{
  "x-generator": "NSwag v11.18.6.0 (NJsonSchema v9.10.67.0 (Newtonsoft.Json v11.0.0.0))",
  "swagger": "2.0",
  "info": {
    "title": "My Title",
    "version": "1.0.0"
  },
  "produces": [
    "text/plain",
    "application/json",
    "text/json"
  ],
  ...
}

swagger.json when I add the new controller

{
  "x-generator": "NSwag v11.18.6.0 (NJsonSchema v9.10.67.0 (Newtonsoft.Json v11.0.0.0))",
  "swagger": "2.0",
  "info": {
    "title": "My Title",
    "version": "1.0.0"
  },
  "consumes": [
    "multipart/form-data"
  ],
  "produces": [
    "text/plain",
    "application/json",
    "text/json"
  ],
  ...
}
