Pydantic raises many logs at runtime

/venv/lib/python3.11/site-packages/pydantic/_internal/_fields.py:132: UserWarning: Field "model_name" in run_own_model_attack has conflict with protected namespace "model_".

You may be able to resolve this warning by setting `model_config['protected_namespaces'] = ()`.
  warnings.warn(

And sometimes causes an error that prevents tools from running. For instance, check this Error Traceroute (raised after asking to run promptmap on mistral as soon as agent started up)
