Fix NotImplementedError

✅ Solution

The "NotImplementedError" in pydantic typically arises when an abstract method or functionality relying on newer Python features (like generics or specific library versions) is not yet fully implemented for the current Python environment. Address this by upgrading pydantic to the latest version, and ensure your Python version meets the minimum requirements for the features being used, potentially updating Python if needed. If the error persists, investigate if the method call is expected to be available or an abstraction that should be implemented by a subclass, and adjust your expectations or provide the specific implementation.
