Fix ValueError

✅ Solution

ValueError errors in Langchain often arise from incorrect data types or missing keys when initializing components like chains or models from dictionaries or configuration files. Ensure that all required parameters are present and of the correct type (e.g., string, integer, list) as expected by the Langchain class constructor. Review the documentation for the specific class to verify the expected data structure and types, and correct any mismatches in your code or configuration.
