[Solved] Given this LangGraph snippet:nodeA.connect(nodeB) nodeB.connect(nodeC, condition=lambda x: x == 'yes') nodeB.connect(nodeD, condition=lambda x: x == 'no')What happens if nodeB receives input 'no'? | LangChain

LangChain - LangGraph for Stateful Agents

Given this LangGraph snippet:

nodeA.connect(nodeB)
nodeB.connect(nodeC, condition=lambda x: x == 'yes')
nodeB.connect(nodeD, condition=lambda x: x == 'no')

What happens if nodeB receives input 'no'?

AThe flow moves from nodeB to nodeD.

BThe flow moves from nodeB to nodeC.

CThe flow stops at nodeB with no next node.

DThe flow moves back to nodeA.

Step-by-Step Solution

Solution:

Step 1: Analyze connections from nodeB
nodeB connects to nodeC if input is 'yes', and to nodeD if input is 'no'.
Step 2: Apply input 'no' to conditions
Input 'no' matches the condition for nodeD, so flow moves to nodeD.
Final Answer:
The flow moves from nodeB to nodeD. -> Option A
Quick Check:
Input 'no' triggers nodeD path [OK]

Quick Trick: Match input to condition to find next node [OK]
