How to pass param n to ChatSparkLLM.generate()

[chansonzhang]

param n is widely supprted by LLM clients to specify how many completions to generate for the conversation.
e.g.

• OpenAI
• vLLM

So, how can I pass n to ChatSparkLLM.generate()

When I use

spark = ChatSparkLLM(n=2, <other params ommitted>)

It report sparkai.errors.SparkAIConnectionError: Error Code: 10004, Error: SchemaCheckError:(14:37:32.934) '$.parameter.chat.n' unknown field;

When I use

spark.generate([messages], callbacks=[handler],n=2,)

It just doesn't work.
