[Solved] Identify the error in this Langchain routing code snippet:def route_condition(context): if context['value'] > 10: return True elif context['value'] | LangChain

LangChain - LangGraph for Stateful Agents

Identify the error in this Langchain routing code snippet:

def route_condition(context):
  if context['value'] > 10:
    return True
  elif context['value'] < 5:
    return False

routes = ['path1', 'path2']
# Routing uses route_condition

ARoutes list should have three paths

BThe function uses wrong comparison operators

CThe function does not return a value for all cases

DThe function should return strings, not booleans

Step-by-Step Solution

Solution:

Step 1: Check function return paths
The function returns True if value > 10, False if value < 5, but returns nothing if value is between 5 and 10.
Step 2: Understand routing condition requirements
Routing conditions must return a boolean for every input to decide path. Missing return causes errors or unexpected behavior.
Final Answer:
The function does not return a value for all cases -> Option C
Quick Check:
All code paths must return a boolean [OK]

Quick Trick: Ensure all if/else paths return a value [OK]

Common Mistakes:

MISTAKES

Ignoring missing return in some cases
Thinking routes count must match conditions exactly
Returning wrong data types
