Error throwing when accessing LinkFactory method in ALM

Hi All,

I am getting an error for the below code.

Set Runs = Test.RunFactory.NewList("")                
For Each Rund In Runs
If Rund.Field("RN_Status") = "Failed" Then
MsgBox ("Successfully found out the failed run")

Set LnkFact = Rund.BugLinkFactory

Set abc = LnkFact.NewList("")

The error is thrown at the last line which states Method 'NewList' of object 'ilInkFactory' failed

Does someone knows the rootcause of the error and what is the right code to achieve the result?
