I can not get my list through the List.filterbyboolmask 2

[kamuYAGW8]

Hi Folks, I am trying to get a set of values through the List.filterbyBoolMask node (at the attached picture, the reed circle), when my filter finds a value of#QQC60060 (at the picture, the value with the blue line) in the same set of values. I’m only getting own value through my filter node…

Can anybody help ?

Regards,
KAMU

There are nulls in your lists
Replace the null in your lists like this
The first code block is not needed and from an old version
