I don't know if it's a version update of the library, or if it's my configuration problem, I need to re-enforce the type definition in all utility classes, such as:

class GoogleSearchTool(ToolInterface):
"""Tool for Google search results."""

name:str = "Google Search"
description:str  = "Get specific information from a search query. Input should be a question like 'How to add number in Clojure?'. Result will be the answer to the question."

def use(self, input_text: str) -> str:
    return search(input_text)`
