Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

# llm = ChatOpenAI()

db = SQLDatabase.from_uri("sqlite:///../somedb/db.sqlite")

agent_executor = create_sql_agent(
    llm=llm,
    db=db,
    verbose=True,
)
agent_executor.handle_parsing_errors=True

resp = agent_executor.invoke("查询三分球命中率最高的球员")
print(resp)

Description

I am using sql_agent at an example time, when the agent is currently running, it is not possible to run the program.

My current LLM analysis calculation time is likely to be a hit. includes_answer = FINAL_ANSWER_ACTION in text Use includes_answer == True ,then the result is FINAL_ANSWER_AND_PARSABLE_ACTION_ERROR_MESSAGE

Can you try the following:

from langchain_community.utilities import SQLDatabase
from langchain.agents import create_sql_agent
from langchain_openai.chat_models import ChatOpenAI
llm = ChatOpenAI(model="gpt-4")
db = SQLDatabase.from_uri("sqlite:///Chinook.db")
agent_executor = create_sql_agent(
    llm=llm,
    db=db,
    verbose=True,
    agent_executor_kwargs={
        "handle_parsing_errors": True
    }
)
resp = agent_executor.invoke("How many customers are only?")
print(resp)

I think it may be the problem with the prompt words, Make Action and Final Answer appear in the same answer.
