What it means

Error "ask_user_question requires at least one question" thrown in deepseek-ai/deepseek-harness.

Source

Thrown at packages/interaction/user-questions/src/index.ts:97

   *
   * When a caller supplies an agent, human interaction is valid only for the
   * exact live runtime root. Runtime ownership, not durable session lineage,
   * decides this boundary: an owned child has no human answerer and would
   * block forever, while a lineage-bearing session resumed as a new runtime
   * root may ask normally.
   *
   * @param request Questions, owner agent, and abort signal.
   * @returns The answer chosen or typed by the human.
   * @throws {UserQuestionError} code `CALLER_NOT_LIVE` when a supplied
   *   agent is not the registry's exact live instance, or `DELEGATED_CALLER`
   *   when that live agent is owned by another agent.
