Yes, Qlik Sense has specific defaults that trigger a connection reset for massive uploads. The Repository Service (QRS) typically has an internal timeout (often defaulting to 90 seconds) and a maximum message size limit (often 2 GB) managed via the Repository.exe.config file. Furthermore, if you are routing through the Qlik Sense Proxy Service, it may drop the connection if the request exceeds its own timeout or buffer limits. To handle 3 GB+ files, you usually need to increase the MaxReceivedMessageSize in the config files or, more reliably, use a chunked upload approach to bypass single-request payload restrictions voyafinancialcom
Thank you for your reply, but I haven't found any suitable settings in Repository.exe.config to resolve the issue. MaxReceivedMessageSize is a QView parameter (which serves a different purpose), and using a block upload approach isn't possible: /app/import uses a filename; the file isn't sent there.
var path = @"C:\Tmp\MyApp.qvf";
var restClient = new RestClient(url);
restClient.AsNtlmUserViaProxy(certificateValidation: false);
var fileStream = new FileStream(path, FileMode.Open, FileAccess.Read);
var streamContent = new StreamContent(fileStream);
streamContent.Headers.ContentType = new MediaTypeHeaderValue("application/vnd.qlik.sense.app");
Console.WriteLine(restClient.PostHttp("/qrs/app/upload?keepData=true&name=" + Path.GetFileName(path), streamContent));
Oh! You get that error using /app/import? Typically that endpoint is much quicker. I just tested and was able to import a 7 GB app without any problem. It took about two minutes with no special configurations in place in my installation.
