Short description of error
When you edit a nodegroup, if the nodegroup is not the active node and you want to add a reroute in the group it raises an error :

Traceback (most recent call last):

windows64\2.83\scripts\addons\node_wrangler.py", line 2939, in execute
    nodes, links = get_nodes_links(context)

    tree = tree.nodes.active.node_tree
AttributeError: 'ShaderNodeRGB' object has no attribute 'node_tree'

Exact steps for others to reproduce the error

No relation with the node wrangler addon but as reported in blender/blender#75680, when you open the attached blend file you can see the nodegroup user count is false.

@Jean-YvesGrosbeau Do I understand correctly that the error only occurs in this file because it was corrupt by blender/blender#75680?

No there is nothing to do with blender/blender#75680. It happens e.g. , when you have several node editors in your interface at the same time, and in one of them you have a nodegroup in edit mode and in the other node editor another node, which is not a group, is selected. So when you try to add the reroute in the group in edit mode the code try to edit to the selected node which is not the nodegroup in which you want to add the reroute.
