{"answer":"Recommended action: Repair the thread state: get_state(config), add ToolMessages for the dangling tool_call_ids (or strip them from the AIMessage), update_state(config, {'messages': ...}), then resume with graph.invoke(None, config).\n\nOption: Patch dangling tool calls in thread state then resume [evidence: official_recommended_action]\nApplies when: Threads interrupted between model and tools nodes\nSteps:\n1. state = graph.get_state(config)\n2.
