Yeah, troubleshooting GN is not easy.
It took me also a while to figure this one out (although, when you know it, it’s simple, but you just don’t know immediately where to look). I worked my way backwards through the Nodes to see what could be the problem.
It can be a wrong Node, like in this case, but it can also be a wrong connection somewhere, or (and this can be really hard to figure out) a problem with the logic.
With time you’ll get more comfortable with the system.
