THEN Before serializing memory with json.dumps, convert the memory dictionary using to_dict() and then serialize the resulting dict. Alternatively, implement custom to_dict() and from_dict() methods on ChatCompletionMessageToolCall for full round-trip support. For persistence, use pickle.dumps on the memory dict.

memory_dict = agent.memory.to_dict()
json_str = json.dumps(memory_dict)  # now works
# Or use pickle for binary serialization:
import pickle
pickled = pickle.dumps(agent.memory.to_dict())
