Error: Unknown exception

[A-MMartin]

Hi,
I have imported successfully the script CodeFlow.js via .scriptload but I'm not able to get the control flow from certain address using "dx Debugger.Utility.Code.TraceDataFlow(address)" or its alias !dflow address. All I get are errors like:

Error: Unknown exception [at CodeFlow (line 734 col 9)]

Not sure if the address format is correct (0x00414122, 00414122) or the error is caused by another problem. I have tried with addresses and symbols from different processes (x86 and 64) with no luck. Could you please set any example along with the output. I haven't found anything.

I'm using WinDBG Preview (1.0.1910.03003) from Windows 10.
Thank you
