[Bug]: [FromForm(Name = "file")] parameter

[Lean365]

Describe the bug

When using the [FromForm(Name = "file")] parameter, the swagger error code is as follows.

public IActionResult ImportData([FromForm(Name = "file")] IFormFile formFile)
{
            List<MmMarbDto> list = new();
            using (var stream = formFile.OpenReadStream())
            {
                list = stream.Query<MmMarbDto>(startCell: "A1").ToList();
            }

            return SUCCESS(_MmMarbService.ImportMmMarb(list.Adapt<List<MmMarb>>()));
}

Failed to generate Operation for action - Ams.WebApi.Controllers.Routine.InstCorpController.ImportData (Ams.WebApi). See inner exception

public IActionResult ImportData(IFormFile formFile)//[FromForm(Name = "file")]
{
            List<MmMarbDto> list = new();
            using (var stream = formFile.OpenReadStream())
            {
                list = stream.Query<MmMarbDto>(startCell: "A1").ToList();
            }

            return SUCCESS(_MmMarbService.ImportMmMarb(list.Adapt<List<MmMarb>>()));
}

Please provide a minimal reproducible example as a GitHub repository that demonstrates the issue you're experiencing so we can look into this further.

The code snippet as-written isn't particularly useful for debugging as it references code you haven't provided.

Also provide details of the inner exception mentioned in the error, particularly its stack trace.

@Lean365 From v6.6.x and onward Swashbuckle will throw an error when a user uses FromForm attribute with IFormFile in controller methods.
