The BDL function CitrixConnect does not work for Citrix load testing in Citrix Receiver 4.4, 4.10 and newer. This is due to a defect in these Citrix versions.
Option 1: Use Citrix Receiver (LTSR) 4.9.7 or later.
Option 2: Use the latest Citrix Workspace-App.
Option 3: Use CitrixConnectIcaData or CitrixConnectIcaFile instead of CitrixConnect.
