We are using the Qlik Sense .NET Framework API to automate Qlik Sense Application Executions.
We have it working fine, but the user that we are using to authenticate with will get the
Multiple Parralell sessions error. This is simply getting application list and variables for a selected application.
I am using the ILocation class to do the app query and it works fine. I also am doing a Dispose on the object after use.
The issue is this: After so many calls to the API, we will get the Max Sessions error, like the Qlik server is not
releasing the connection.
Now the question: How can I get Qlik Sense to release the connection when I am done with the ILocation interface?
Here is an example of the code for getting the app list objects:
ILocation _location = null;
List<IAppIdentifier> _allApps = null;
try
{
_location = Qlik.Engine.Location.FromUri(new Uri($"wss://{qlikServer}"));
NetworkCredential cred = new System.Net.NetworkCredential(userLoginName, password, "DOMAIN");
_location.AsNtlmUserViaProxy(false, cred, true);
//Do operation (In this case get the app list)
_allApps = new List<IAppIdentifier>(_location.GetAppIdentifiers());
}
catch (Exception ex)
{
//Handle Exception
}
finally
{
if(_location != null)
_location.Dispose();
}
This example is getting the ap list from the location. But if I did this a few more times, it will give the Max Session error like the WebSocket is not releasing its connection.
Thanks,
Ben
