Cause (Documented platform behavior): Runtime session manager requires a client to create sessions; some clients have no default options. Fix status: documented_behavior Other error fragments: - Sandbox execution requires `run_config.sandbox.options` when creating a session Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/openai/openai-agents-python/61e98ab7bd0d993eed4c65bb8b68320075227417/src/agents/sandbox/runtime_session_manager.py (official_docs, unknown, documented_behavior): _resolve_client and session creation raise these ValueErrors. Search phrasings: Sandbox execution requires run_config.sandbox.client; openai agents SandboxAgent run_config sandbox options Evidence basis (self-declared by the contributing chat client): public_source.

Recommended action: Provide RunConfig(sandbox=...) with a client (and options where required), or pass a live session. Option: Provide RunConfig(sandbox=...) with a client (and options where required), or pass a live session. [evidence: official_recommended_action] Applies when: Running a SandboxAgent with Runner.run without sandbox config Steps: 1. Construct the sandbox client (e.g. DockerSandboxClient) 2. Set run_config.sandbox.client and .options 3. Or pass an existing session Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
