当从 run as a function 发生异常时，例如 content management policy 触发的异常导致所有节点输出丢失：

f = load_flow(source="../../examples/flows/chat/chat-basic/")
f.context.streaming = True
try:
  result = f(
      chat_history=[
          {
              "inputs": {"chat_input": "Hi"},
              "outputs": {"chat_output": "Hello! How can I assist you today?"},
          }
      ],
      question="How are you?",
  )
except WrappedOpenAIError as exc:
  # we lost succeeded node output as well
  pass

answer = ""
# the result will be a generator, iterate it to get the result
for r in result["answer"]:
    answer += r

描述您希望的解决方案

当发生异常时，我们是否可以将某些节点输出保存在某个地方？例如：node1->node2->node3 当 node2 触发异常时，我们仍然可以从 node1 获得输出吗？
