Created image through media service - it's not working

[simoazzo]

I am trying to create an image programmatically, but the image being uploaded on AWS S3 bucket is becoming as 0KB, so no image is being uploaded.

Any clue?

This is the code:

if (imageBytes != null & imageBytes.Any())
                    {
                        var imageAsIMedia = mediaService.CreateMedia(item.title, new Guid(Constants.Constants.CommunityItemsFolderGuId), global::Umbraco.Core.Constants.Conventions.MediaTypes.Image);

                        using (Stream stream = new MemoryStream(imageBytes))
                        {
                            var imageFromStream = Image.FromStream(stream);
                            var imageFormat = ImageHelpers.GetImageFormat(imageFromStream);

                            imageAsIMedia.SetValue(Services.ContentTypeBaseServices, "umbracoFile", item.title + imageFormat, stream);

                            var imageSaveResult = mediaService.Save(imageAsIMedia);
                            if (imageSaveResult.Success)
                            {
                                request.SetValue(Constants.Constants.CommunityItemPhotoAlias, imageAsIMedia.GetUdi());

                                var mediaAsIPublishedContent = Umbraco.Media(imageAsIMedia.Id);

                                imageUrl = mediaAsIPublishedContent.Url(null, UrlMode.Absolute);
                            }
                        }
                    }
