Good Day
Please tell me, I get this message when I run the fixlet. How to fix it?
I have BigFix Console version 10.0.2.52

@darksmoke This looks like a gathering error for a BigFix site that I am not familiar with.
Suggest you open a trouble ticket at https://support.bigfix.com

In the meantime, some searching shows a few possible alternatives
