(500) Internal server error on deleting files

I am unable to delete the 6 files that tus creates when for each uploaded file. I am pretty much using the TusClient and TusHttpClient from Tus.io

On the odd occasion it does actually delete the files but 95% of the time I get an internal server error.

2019-07-30 12:15:54.1926 ERROR [8:] TusFileTransferClient.TusHttpClient.PerformRequest TusException : TusFileTransferClient.TusException: The remote server returned an error: (500) Internal Server Error. —> System.Net.WebException: The remote server returned an error: (500) Internal Server Error. at System.Net.HttpWebRequest.GetResponse()

var file = new FileInfo(filename);
var client = new TusClient();
var metaData = new Dictionary<string, string>
{
   {"product", _fileRetrievalInfo.DisplayName},
   {"fileType", _fileRetrievalInfo.RetrievalType.ToString()}, 
   {"id", _surveyor.Id.ToString()}
};
var fileUrl = client.Create(uploadAddress, file, metaData);
client.Upload(fileUrl, file);
client.Delete(fileUrl));

So whilst I have not managed to get a proper error message I have found the cause. It was obviously me being a dufus!

So in this code to save the uploaded file

using (var output = new FileStream(localFilename, FileMode.Create))
{
   var uploadedFile = await file.GetContentAsync(token);
   Log.Debug($"---> Received uploaded file, CopyTo {localFilename}");
   uploadedFile.CopyTo(output);
   await output.FlushAsync(token);
   output.Close();
   uploadedFile.Close();   <-----
}

I had forgotten to close the file.

Perhaps some error checking around the file deletion so it can give a better error message for idiot users like me?

Thanks for all your help it works perfectly now

I haven’t as yet I am afraid I was dragged off the project for a week or so. I am back on it now and will try tomorrow to get the logs. The project I am working on is using asp.net and mvc 5 so will have to work out how to get global error handlers for it as I believe its not as easy as core.

I have however found that sometimes it does delete the files without errors, not often but sometimes. I suspect something is keeping the file open or some such.

Thanks
