Qlik Sense .Net SDK Timeout

[mstoler]

Hello,

I am using the Qlik Sense .Net SDK to load an Application.

Sometimes when I use the statement below to load an app I get a Timeout Exception.  Is there a way to set the Timeout Value?

ILocation location = Qlik.Engine.Location.FromUri(new Uri(sQlikSenseServer));

location.AsNtlmUserViaProxy(proxyUsesSsl: false);

IAppIdentifier appIdentifer = location.AppWithNameOrDefault(sQlikSenseApplication);

var app = location.App(id);    // This statement sometimes gets a Timeout Exception

Thank You,

Yes, there is a setting for it. You can use this one:

It's a static, global property so you can set it directly. If you don't care about timeouts, you could write like this:

JsonRpc.Timeout = Int32.MaxValue;

Another option would be to use the async version of App. That way you can control the timeout behavior yourself:

I am calling the same app multiple times and it gives an exception on the 4th call. "Websocket closed unexpectedly(endpoint unavailable)"
var location = Location.FromUri(_baseUrl);
location.AsJwtViaProxy(token);
IAppIdentifier foundAppIdentifier = location.AppWithNameOrDefault(appName);

using (var app = await location.AppAsync(foundAppIdentifier.AppId)){}

//I used debug console and found this:
