Can not upload image with null Reference exception

[trktuhin]

My code is completely similar to yours. I have only one issue testing the photo upload api. It seems like my api is not getting a IFormFile object from the body of the request. Here's the proof: This is the action: ` [HttpPost] public async Task<IActionResult> Upload(int vId,IFormFile fileStream) { var vehicle = await this.repository.GetVehicle(vId, hasAdditional: false); if (vehicle == null) return NotFound(); var uploadsFolderPath = Path.Combine(host.WebRootPath, "uploads"); if (!Directory.Exists(uploadsFolderPath)) Directory.CreateDirectory(uploadsFolderPath); var fileName = Guid.NewGuid().ToString() + Path.GetExtension(fileStream.FileName); var filePath = Path.Combine(uploadsFolderPath, fileName);

    using (var stream = new FileStream(filePath, FileMode.Create))
    {
        await fileStream.CopyToAsync(stream);
    }

    var photo = new Photo { FileName = fileName };
    vehicle.Photos.Add(photo);
    await unitOfWork.CompleteAsync();
    return Ok(mapper.Map<Photo,PhotoResource>(photo));
}

and the controller with constructor: public class PhotosController : Controller { private readonly IHostingEnvironment host; private readonly IVehicleRepository repository; private readonly IMapper mapper; private readonly IUnitOfWork unitOfWork;

    public PhotosController(IHostingEnvironment host, IVehicleRepository repository,IUnitOfWork unitOfWork, IMapper mapper)
    {
        this.mapper = mapper;
        this.repository = repository;
        this.host = host;
}`

error shows on this line:

    var fileName = Guid.NewGuid().ToString() + Path.GetExtension(fileStream.FileName);

which indicates its not getting the "file" object while I am sending an image.jpg with the same key "fileStream".
