Fix ForkDepthExceededError
in LangChain
✅ Solution
The ForkDepthExceededError in Langchain usually arises when recursive calls to agents or chains create an excessively deep call stack exceeding Python's recursion limit. To fix this, either restructure your chains to use iterative rather than recursive logic, or increase the Python recursion limit using `sys.setrecursionlimit(new_limit)`, although the latter should be done cautiously and with consideration for system memory. Consider refactoring to employ a queue or similar approach for managing the workflow instead of deep recursion.
