get_symbols_tool failing silently.

[Zendhil]

Hi.. Thanks very much for this package. I am trying to use your tool to extract symbols. and the function is failing silently. Below is the log. the other tools get_function_tool and get_class_tool are working... i am scanning a python file. Please let me know if there is something i need to do. Thank you. Appreciate any response. i am using mcp-server-code-extractor, Version: 0.4.2
