So as I said in my previous post I back tracked to creating my first node with keyframes again.
It works but I can't see the curves on the graph editor now. How do I make them visible?
I ran into this exact problem. Turns out I had the node selected in the shader editor, but I did not have the plane object selected in the scene. Took an embarrassing amount of time to figure that one out :)
This answer helped me out too. Was pulling my hair for several minutes on why I could not see the nodes.
