langchain and pydantic compatible version?

[Typhoona]

Thanks for your excellent work.
When i run your code, I meet some errors that i am confused how to tackle.
Now in my envs,
langchain 0.1.14
langchain-community 0.0.31
langchain-core 0.1.40
langchain-text-splitters 0.0.1
langchainhub 0.1.21
langdetect 1.0.9
langsmith 0.1.40
and pydantic version：
pydantic 2.6.1
pydantic_core 2.16.2
pydantic-settings 2.2.1
But the error is:
raise OutputParserException(f"Could not parse function call: {exc}")
langchain_core.exceptions.OutputParserException: Could not parse function call: 'function_call'

The above version is the same as your given yml file.
Can you give me some advice?
