我试图为我的服务生成swagger规范，它失败了这个错误。

Error: Swagger schema validation failed.
  Data does not match any schemas from 'oneOf' at #/paths//abc/{id}/createFile/post/parameters/3
    Data does not match any schemas from 'oneOf' at #/paths//abc/{id}/createFile/post/parameters/3
      Missing required property: schema at #/
      Data does not match any schemas from 'oneOf' at #/
        Additional properties not allowed: properties at #/items
        Additional properties not allowed: properties at #/items
        Additional properties not allowed: properties at #/items
        Missing required property: required at #/
    Missing required property: $ref at #/paths//abc/{id}/createFile/post/parameters/3

如果从InputClass中删除AdditionalInput属性，则Swagger规范生成成功。应该采取什么措施来解决此问题？

public class InputClass
{
    public IFormFile File { get; set; }
    public string Name { get; set; }
    public List<CustomKVP> AdditionalInput { get; set; }
}

public class CustomKVP
{
    public string Name { get; set; }
    public string Value { get; set; }
}

[HttpPost]
[Route("abc/{id}/createFile")]
[SwaggerOperation(OperationId = "createFile")]
public async Task<IActionResult> CreateFileAsync([FromRoute] string id, [FromForm] InputClass inputClass)
{
}

此外，如果我将FromForm更改为FromBody，则会创建Swagger Spec。
Swagger JSON，输入对象为FromForm

在Swagger UI上遇到错误。
