Client cant show file

Question

Hi, I'm trying to do basic things in Adobe Drive SDK. I don't have implemented any server, but I want Adobe Drive Client to show me some "Files" (which in fact doesnt exists). I implemented a GetChildrenHandler and was successfull tu create my own root folder or folder under root folder and so on, but it doesn't work with files. There is a condition in the code, that if a parent is the root, client should create new folder under this root (that works fine). Then, if the folder is not root, I want to tell to client, that it has to show me a file, but this is the part, which doenst work to me. Can you, please, help me? Here is the part of code, which should be done, if parent folder is not root. Thanks
String assetId =  parentPath.toString() + "/test.png"
                String parentId = parentPath.toString();
                    Path path = Path.newInstance(assetId);
                UpdateRecipe recipe = response.createFileUpdateRecipe(
                        assetId,
                        path,
                        parentId,
                        1,
                        new ETags());
                long lastModified = System.currentTimeMillis();
                long j = 123456;
                Long fileSize = j;
                String comment = null;
                String modificationUser = "User";
                Flags flags = null;
                MimeType mimeType = MimeType.IMAGE_PNG;
                long eTagValue = System.currentTimeMillis();
                recipe.getIdentificationData().getETags().put(DataType.BASIC, new ETag(eTagValue));
                recipe.createBasicData(
                        lastModified,
                        lastModified,
                        fileSize,
                        comment,
                        new User(modificationUser),
                        Visibility.VISIBLE,
                        flags,
                        mimeType,
                        null);
And this if from log:

I would suggest getting assistance from the Adobe Developer Support team for this inquiry if you don’t get a response. This team helps address questions/issues folks are having related to the Adobe Drive SDK. Developer Support is available via membership to the Adobe Technology Partner Program or via an Adobe Developer Support single support incident or bundle of incidents: http://www.adobe.com/support/programs/developer
Are you in the process of creating a custom connector for Adobe Drive that will connect to a particular DAM server or?
