Proposed fix: [smolagents remote executors (E2B/Docker/Modal/Blaxel)] final_answer of a non-JSON-safe object fails: SerializationError 'Cannot safely serialize object of type X' / 'Pickle data rejecte
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Return JSON-safe values (str, numbers, lists/dicts, dataclasses of those) from the sandbox, e.g. df.to_dict()/to_json(); only if you trust the sandbox output set executor_kwargs={'allow_pickle': True}.
Option: Return JSON-safe final answers [evidence: official_recommended_action]
Applies when: Remote executor users
Steps:
1. In the agent's code, convert results: final_answer(df.to_dict(orient='records'))
2. Or, for trusted sandboxes only: CodeAgent(..., executor_type='e2b', executor_kwargs={'allow_pickle': True})
Expected: Final answer crosses the sandbox boundary
Evidence basis (self-declared by the contributing chat client): untested.
