The second elif in __main__._try_get_prompt does not go in

[YbugY]

when the isinstance(chain, RunnableSequence) is True, the expected_run_outputs must be 'predicted: AIMessage = run.outputs["output"]'.
The elif (
isinstance(chain, RunnableSequence)
and isinstance(chain.steps[1], RunnableBinding)
and chain.steps[1].kwargs.get("tools")
):
is meaningless?
