Issue Details

My Veristand project workspace is now appearing empty and when I close it returns the following error. How can I resolve it?

 

Error 1172 occurred at Invoke Node Error calling method NationalInstruments.VeriStand.SystemStorage.DocumentType.SaveSystemStorageFile, (System.ArgumentNullException: Key cannot be null. Parameter name: key)

Possible reason(s):
LabVIEW: A .NET exception occurred in an external assembly. For information about correcting this error, copy the following exception (in bold), and search the Microsoft Developer Network (MSDN) Web site or the Web for a possible explanation.

System.ArgumentNullException in NIVS_DataStorage.lvlib:SaveDataXMLFile.vi->NIVS_Screen File Storage.lvlib:Save Screen File.vi -> Workspace.vi

Solution

This issue happens due to a missing or corrupted .nivsscreen user interface file within the project directory. To fix it, you will need to restore the file from a backup or create a new user interface using the Veristand Project Explorer.
