Fix PydanticUserError

✅ Solution

PydanticUserError usually arises from using pydantic features incorrectly, often due to type annotation errors or incompatible usage patterns with new Pydantic versions. Review your model definitions, especially custom validators, RootModel usage, and discriminators defined with Literal, ensuring everything aligns with the expected format as per the Pydantic documentation. Correct type annotations and adapt incompatible code patterns to resolve these user errors.
