langchain ValueError: Got unsupported early_stopping

Using early_stopping_method with "generate" is not supported with new addition to custom LLM agents. More specifically:

agent_executor = AgentExecutor.from_agent_and_tools(agent=agent, tools=tools, verbose=True, max_execution_time=6, max_iterations=3, early_stopping_method="generate")

I also encountered this problem. Looking at the source code, I found that langchain does not currently support this parameter.

Hi, @assafelovic,

I'm helping the LangChain team manage their backlog and am marking this issue as stale. It looks like you opened an issue regarding a ValueError encountered when using the early_stopping_method "generate" with a custom LLM agent. Several users, including alex14dark and ChalamPVS, have reported encountering the same issue and are seeking a resolution.

Could you please confirm if this issue is still relevant to the latest version of the LangChain repository? If it is, please let the LangChain team know by commenting on the issue. Otherwise, feel free to close the issue yourself, or it will be automatically closed in 7 days. Thank you!
