When working on a vehicle, if you attempt to replace a component that is not properly defined or compatible with the vehicle's make and model, you may encounter issues. What error is typically raised by the diagnostic tool when such situations occur, and how can you use this information to prevent potential damage to the vehicle?
### Response:
import networkx as nx

try:
    G = nx.Graph()
    # This will raise an exception because 'node_for_adding' is not defined
    G.add_node(node_for_adding)
