Hey Jainesh, the problem is in the following lines: graph.add_edge("node_3", "node_4") graph.add_edge("node_3", "node_5") graph.add_edge("node_3", "node_6") graph.add_conditional_edges("node_3", condition_node3) graph.add_edge("node_4",END) graph.add_edge("node_5", END) graph.add_edge("node_6", END) After node_3 you always enter node_4, node_5 and node_6 in parallel as they are all connected via an edge to node_3. Afterwards, you have an extra conditional edge to all 3 nodes, which explains...
