Example Code

cypherChain = GraphCypherQAChain(allow_dangerous_requests=True).from_llm(
    ChatOpenAI(temperature=0),
    graph=kg,
    verbose=True,
    cypher_prompt=CYPHER_GENERATION_PROMPT,
)

Description

I'm trying to use GraphCypherChain but is gives me this error. I need exact syntax to use allow_dangerous_requests parameter.
In order to use this chain, you must acknowledge that it can make dangerous requests by setting allow_dangerous_requests to True.You must narrowly scope the permissions of the database connection to only include necessary permissions. Failure to do so may result in data corruption or loss or reading sensitive data if such data is present in the database.Only use this chain if you understand the risks and have taken the necessary precautions. See https://python.langchain.com/docs/security for more information.

@awais019 I think you are misunderstanding the class. You should use GraphCypherQAChain() when you need to explicitly create an instance of the class. However, if you just need to quickly set up the chain using an LLM, you can use the from_llm method, like this:

cypherChain = GraphCypherQAChain.from_llm(
    ChatOpenAI(temperature=0),
    verbose=True,
    allow_dangerous_requests=True,
    graph=kg
)
