Quite a minor one, but if you look at the Python tooltip of a node value in a Material, Texture, or Compositor tree it will start with something like bpy.data.node_groups["Compositing Nodetree"]. It's not there! The tree is actually a property of the mat/tex/scene.
Exact steps for others to reproduce the error
- Create a Material, Texture, or Compositor node tree
- Hover over any property UI element
