C# API : Unable to find batch with id batchId-xx-xx-xx

Question

Hi everybody,

I'm having trouble uploading files with the Uploader object.
Here's how I do it :
I have a class dedicated to managing REST operations in which I created the methods.

* At instanciation :
public TransferFactory(Client client){
uploader = client.Uploader().SetChuncked(true).SetChunkSize(1024);
}

* Files import :
public void ImportFile(string[] pathes, Document folder)
{
System.Threading.Tasks.Task.Run(async () =>
{
await uploader.AddFiles(pathes).UploadFiles();
Documents documents = (Documents) await uploader.Operation("FileManager.Import")
.SetContext("currentDocument", folder.Path)
.Execute();
Console.WriteLine("Done.");
}).Wait();
}

When I need to create a folder, (not described here method) it works well.
But when I need to upload files, I have the error : C# API : Unable to find batch with id batchId-xx-xx-xx

Any help would be welcome,
Thank's in advance !

I finaly found what was going wrong.

The uploader was created once at instanciation and it seems that it disappears during the processing of my program.
I guess it's killed for security reason or anything.

So the answer was :
Create a new uploader each time the ImportFile method is called.

That's it, thanks for your reflexion.
