When using chunked upload the success response body is always empty

[Bram]

I am using the TelerikUpload component with UploadChunkSettings defined.
Telerik.UI.for.Blazor version 9.0.0

When not using a chunked upload I can return a response body a read it in the success handler, however when code was changed to use chunks the response body is always empty.

Is this a bug when using chunked upload, or do I need to return a different response in the Controller?

 

Code from the save method in Api Controller:

string chunkMetaData = formData["chunkMetaData"].ToString();

ChunkMetaData chunkData = JsonConvert.DeserializeObject<ChunkMetaData>(chunkMetaData);

// Append chunks to file
// ...


if (chunkData.TotalChunks - 1 == chunkData.ChunkIndex)
{
     uploadComplete = true;
     fs.Flush();
}

// More code omitted ...

if (uploadComplete)
{
	Response.StatusCode = StatusCodes.Status200OK;
	await Response.WriteAsync(result.ResultId.ToString());

	return new EmptyResult();
}
else
{
	Response.StatusCode = StatusCodes.Status201Created;
	await Response.WriteAsync("Chunk upload successful.");
	
	return new EmptyResult();
}

 

OnSuccess handler:

protected async Task SuccessHandler(UploadSuccessEventArgs args)
{
	int resultid = 0;

	if (int.TryParse(args.Request.ResponseText, out resultid))
	{
		//  do something with the resultid
		//  ...
		//  args.Request.ResponseText is always empty when using chunked upload
	}
}

Hello Bram,

This was fixed recently and the changes will take effect in the coming release in two weeks.
