Your node expression language is set to Python and $F isn't a valid Python call. If you delete your channels, set the language to Hscript and put it in again it will work.

Thanks! I was losing my mind over this xD

For those looking where to change it globally
edit / preferences / scripting
Expression language menu

For individual nodes (you probably need to reenter expression after switching to another language)

any news?

I'm trying to generate 2 uv sets in a mesh a created in houdini and I have no idea how to do so.

I don't know if I understand you correctly, but now You have to write exactly what uv attribute you want to use.
