Issue, Question or Enhancement:

I have a question. I was writing a REST API server that receives images and stores them in a database.
Convert the client's request to

type ImageCreateRequest struct {
	Name string `form:"name" validate:"required"`
	Description string `form:"description"`
	Image *multipart.FileHeader `form:"image" validate:"required,image"`
}

After receiving this format

	var err error
	if request.Image, err = c.FormFile("image"); err != nil {
		return nil, err
	}

	if err := validator.RequestValidator(request.Image.Filename); err != nil {
		return nil, err
	}

I parsed it this way, and proceeded with the typechecking.
However, interface conversion: error is *validator.InvalidValidationError, not validator.ValidationErrors
(For reference, the framework used gofiber v2.)

I got this error.
I am at a loss to find a solution to this problem.

I would be grateful if you could help me out.
