I am terribly confused why this is not working. I have followed similar examples and failed (i.e. Blender scripting connect nodes)
bpy.context.active_object.active_material.node_tree.links.new(bpy.data.materials["Material.001"].node_tree.nodes["Principled BSDF"].inputs[0], bpy.data.materials["Material.001"].node_tree.nodes["ShaderNodeTexCoord"].outputs[0])
If my code is too difficult to decipher, here's a summary: I am just trying to link the Texture Coordinate node output to the Base Color input of the Principled BSDF.
I wrote out the whole line above without using any variables in the aid of clarity/searchability.
Thank you all!

.from_node.which is not correct offhand. – Ratt Apr 13 '21 at 21:55
