LangChain - LangGraph for Stateful Agents

How can LangGraph handle a scenario where an agent must retry a step up to 3 times before failing?

ACreate a loop by connecting the retry node back to itself with a counter condition.

BUse a single connection without conditions and rely on external retry logic.

CConnect nodes linearly without loops; retries are not supported.

DAdd multiple identical nodes without conditions to simulate retries.

Step-by-Step Solution

Solution:

Step 1: Understand retry logic in flows
Retries require looping back to the same step with a limit on attempts.
Step 2: Implement loop with condition counting retries
Connect the retry node back to itself with a condition checking if retry count is less than 3.
Final Answer:
Create a loop by connecting the retry node back to itself with a counter condition. -> Option A
Quick Check:
Retries = loop with condition count [OK]

Quick Trick: Use loops with conditions for retries [OK]
