External exception E06D7363 while running C# script under TestExecute 8.20

Hi,



I am running a C# script under TestExecute 8.20 and it terminates with a Jscript exception error.



The details from the log are:



External exception E06D7363

Error location:

Unit: "VFASTTestManager\TestManager\Script\Reporting"

Line: 45 Column: 4.



How do I debug this exception? 



Can I add something to my script to get more details so that I can determine the cause?



Any help or ideas is greatly appreciated.



Thanks in advance, JO.
