        return Message(content=message_result.data["text"])

debugger and fix

debugger found get run_outputs result not correctly

1. run_outputs[0].outputs.results is dict type without message attribute 。 so use code get flow result
   _, message_result = next(iter(run_outputs[0].outputs[0].results.items()))

2. return Message Object have text attribute not content attribute
