HttpContext.Current alternative in Owin Self Host?

I am trying to get a File that is being sent (from Postman) in the body of a POST request to my REST API that is self hosted using Owin. While debugging I can confirm that the correct endpoint it being reached but HttpContext.Current returns null always. Pretty much HttpContext.anything returns null. So I don't understand how I am supposed to receive a File via POST request and process it in my REST API while using Owin self hosting. I have tried Request.GetOwinContext() but that doesn't return anything useful.

How do I achieve this?

The Request property of a controller can help access the file.

public class FileController : ApiController
{
    [HttpPost]
    public async Task Post()
    {
        if (Request.Content.IsMimeMultipartContent())
        {
            var multipartContent = await Request.Content.ReadAsMultipartAsync();

            // "thefile" is the form field name
            HttpContent httpContent = multipartContent.Contents
                .Where(c => c.Headers.ContentDisposition.Name == "\"thefile\"")
                .Single();

            // httpContent contains the file, for example:
            var fileContents = await httpContent.ReadAsStringAsync();
        }
    }
}
