Hi everyone,

I'm trying to build my own conversational chatbot. When I run the code above, I got the following output:

```

May I know how can I stop the agent from keep generating new input? I already use the stop parameter, but seems like it doesn't work.

I follow the instruction from Langchain documentation [here](https://python.langchain.com/docs/modules/agents/agent_types/chat_conversation_agent)

Based on the documentation, the output shouldn't return so many New inputs and responses. Any help or advise will be greatly appreciated!
