• response_not_found: The target response is not available on this connection.
• invalid_input: The event or input failed validation.
• steering_not_supported: The model or response execution mode does not support steering.
• too_many_pending_steers: Too much steering input is pending for the response.
• response_already_completed: The response completed and is no longer accepting steering input.
• response_not_active: The response is no longer accepting steering input.
• successor_creation_failed: The successor response could not be created.

A human-readable description of the error.

The error type. Always invalid_request_error.

Input to queue for a continuation of the response. Uses the same string or input-item shape as response.create.input, with a non-empty array when supplying input items.

Steering accepts only messages with the user role. Each message may contain only type, role, and content, with content as a string or an array of input_text, input_image, and input_file parts. The optional type must be message. Other roles, tool outputs, and item types are not supported for steering.

The ID of the response that was targeted for steering.

The ID assigned to the steering submission, if one was allocated.
